(Summary description)Conductive rubber buttons are the process of evenly distributing conductive particles such as silver plated glass, silver plated aluminum, and silver in silicone rubber. Conductive particles achieve good conductivity through pressure contact. However, if you use it for a long time, the key will fail. Replacing a new keyboard is both expensive and uneconomical. If the following methods can be tried for repair, it can not only solve urgent problems but also save unnecessary expenses.

1. Cleaning method

Wipe off the ineffective conductive rubber buttons with anhydrous alcohol. If not, as conductive rubber has a certain thickness, it can be gently wiped several times with fine sandpaper, while carefully wiping the contact between the circuit board surface and the button with rubber.

2. Heat treatment method

Invert the conductive layer and bake it on an electric heater or bright incandescent lamp for a few minutes until it turns white. For conductive rubber buttons with less severe aging, the rubber can also be soaked in boiling water for a few minutes.

3. Conductive adhesive method

The main components of conductive adhesive are resin adhesive and conductive particles, which are powder particles of conductive materials such as gold, silver, copper, iron, aluminum, zinc, tin, graphite, etc. Apply conductive adhesive to the conductive rubber button, and after natural drying, conductive particles will adhere to the conductive rubber, achieving excellent results. The disadvantage of conductive adhesive is that as the buttons wear during use, the conductive film will fall off, causing a short circuit in the buttons.

4. Cutting

Turn on the electrical appliance, remove the key rubber blade, and then remove a new razor blade, scraping a thin layer off the conductive rubber button contact.

5. Aluminum foil method

Cut aluminum foil, tin foil, and other metal parts into button sizes and directly attach them to the failed conductive rubber buttons, or use commonly used aluminum foil tape for plumbing equipment.

6. Application method

Find a 4B or even 6B pencil and rub it a few times on the conductive rubber of the faulty button. Easy to operate and requires minimal materials. The disadvantage is that it is not durable, and pencil powder will still fall off after being used for a long time. If it falls on the circuit board, it may cause other troubles. Of course, you can also paste the powder of the motor brush.

7. Wire method

Take out a single wire from multiple strands of wire, insert one end of the wire into the faulty button with a small flat head screwdriver, use it on the inner surface of the difficult to use key, and then insert the other end at an appropriate distance to form an N-shaped span on the faulty button. The setting method of copper wire is convenient to use and durable. This method is suitable for circuit boards made of copper clad boards with copper foil keyboards, but it is not suitable for keyboards coated with conductive adhesive, as long-term use of this method can damage keyboards coated with conductive adhesive.

8. Replacement method

Carefully cut off the conductive rubber buttons of the non removable conductive keyboard with a knife, and carefully cut off the non replaceable conductive rubber with a knife. Correct the height of conductive rubber and the magnitude of electric shock between them, and then bond them together. This method can take a long time if done manually, but glue is also important.

9. Alternative methods

It is also easier to directly replace the original conductive rubber key contact with the mobile phone's chip key or ordinary Touch switch.

What are acrylic lenses? What are the characteristics and uses?

Acrylic lenses actually refer to PMMA plates after electroplating. Using plastic lenses instead of glass lenses has the advantages of light weight, not easy to break, convenient molding and processing, and easy coloring. The development momentum of acrylic lenses is increasing and has become a technology in lens production. Generally, plastic sheets can be made into single lens, double lens, rubber lens, paper lens, half lens, etc. They can be manufactured according to different requirements, such as the screens of mobile phones and televisions, which can be seen every day. Acrylic lens characteristics: Acrylic is suitable for secondary processing, such as mechanical processing, thermoplastic molding, blow molding, blister molding, solvent bonding, thermal transfer printing, screen printing, vacuum deposition. After success, it is what we call acrylic lenses. Acrylic board is polymerized from methyl methacrylate monomer (MMA), which is also known as polymethyl methacrylate (PMMA) board organic glass. It is a type of organic glass processed through special processes and is known as the "queen of plastics". The research and development of acrylic has a history of over 100 years. Acrylic lens usage: Acrylic has the advantages of light weight, low price, and easy molding. Its molding methods include casting, injection molding, mechanical processing, acrylic hot molding, etc., especially injection molding, which can be produced in large quantities with simple process and low cost. Therefore, its application is becoming increasingly widespread, currently widely used in instrument parts, car lights, optical lenses, transparent pipes, and so on. Acrylic is an ideal new material for manufacturing sanitary ware after ceramics. Compared with traditional ceramic materials, acrylic not only has different high brightness, but also has the following advantages: good toughness, not easily damaged; Strong repairability, as long as the soft foam is dipped in toothpaste, the sanitary ware can be wiped clean; The texture is soft, and there is no cold and piercing feeling in winter; Bright colors can meet personal pursuits of different flavors. Acrylic material washbasins, bathtubs, and toilets are not only exquisitely designed and durable, but also have environmental protection functions, with radiation lines almost identical to human bones. Acrylic sanitary ware first appeared in the United States and now accounts for over 70% of the international market. Due to the difficulty and high cost of acrylic fiber production, many low-quality and low-cost alternatives have emerged in the market. These substitutes, also known as "acrylic", are actually ordinary organic or composite boards. Ordinary organic board is made by casting ordinary organic glass cracking material and pigment, with low surface hardness and easy fading, and poor polishing effect after polishing with fine sand. In the middle, there is only a thin layer of acrylic on the surface of the composite plate of ABS plastic, which is easy to delaminate due to the influence of thermal expansion in use. Acrylic lenses can be distinguished by the subtle color difference and polishing effect of the plate: 1. Architectural applications: windows, soundproof doors and windows, daylighting covers, telephone booths, decorative colored mirrors, etc. 2. Advertising applications: 3360 lightboxes, signs, signs, exhibition stands, etc. 3. Transportation applications: trains, car mirrors, car lenses, etc. 4. Medical applications: baby care boxes, various surgical and medical devices, civilian products: handicrafts. Aquarium, toy mirror, etc. 5. Industrial applications: instrument panels, protective covers, etc. 6. Lighting applications: fluorescent lamps, chandeliers, street lamp lampshades, LED reflective panels, acrylic reflective panels, etc.

What are acrylic lenses? What are the advantages?

As is well known, the material of acrylic lenses is polymethyl methacrylate, abbreviated as PMMA. We usually refer to it as organic glass. After electroplating with PMMA, a mirror effect product is formed. Usually, different mirrors are produced according to customer needs due to different electroplating conditions, such as single-sided mirrors produced by electroplating on one side, double-sided mirrors produced by electroplating on the other side, rubber mirrors produced by electroplating on other different plastics, semi lenses produced by electroplating on semi transparent plastics, paper mirrors, etc. Acrylic lenses are widely used and very convenient to use, so they are loved by people and are also seen and used in our daily lives. Due to its stable chemical properties, it can maintain good stability not only in acidic environments but also in alkaline environments, both acid and alkali resistant. They are called plastic crystals. To put it bluntly, transparent plastic lenses. Due to its stable chemical properties, it is also the preferred choice recommended by the factory to customers. The advantages of acrylic lenses: 1. The transparency can be adjusted according to customer needs, with a transparency of up to 92%, which can generally meet customer needs. 2. Chemical stability is strong, acid and alkali resistance is good, so it will not corrode acrylic lenses due to bad outdoor environment. 3. Replacing glass lenses, as is well known, is a common type of lens. The great advantage of these lenses is their high transmittance, which is commonly used. But there is a particularly big drawback, which is that accidentally breaking it can cause subsequent damage to the human body, but acrylic lenses have overcome this very well. 4. Strong hardness. The acrylic lenses currently used are generally 1 meter high and have no signs of falling on the ground. But if you replace glass lenses, even if they are 20 centimeters high, they can still break into pieces. 5. Good glossiness, the glossiness of acrylic lenses can look 99.99% glossiness, so many people like to use acrylic lenses as trophies, and the ones inside the medals look great. 6. Strong plasticity. After high-temperature heating, acrylic lenses can be modified according to their shape or images can be modified using laser. It can be customized according to needs, very convenient. Comparing acrylic lenses and plastic lenses, it can be found that the effects of the two types of lenses are almost the same. However, specifically, acrylic lenses are more affordable and cost-effective, while PC lenses are relatively expensive and have lower cost-effectiveness than acrylic lenses. The main difference between acrylic lenses and PC lenses lies in their different uses. Acrylic lenses are mainly used in daily life. Due to its high thermal performance, PC lenses are commonly used in space, aerospace, and other fields. It can also be used for bulletproof purposes. So according to their respective performance, there are different prices and market uses. In terms of processing, acrylic lenses are relatively easy to process, while plastic lenses are relatively troublesome to process. At present, acrylic lenses can be made through mechanical processing, thermoplastic molding, blow molding, plastic molding, solvent bonding, hot stamping, screen printing, and main vacuum electroplating methods, making secondary processing more convenient.

Production process and application fields of conductive rubber buttons

Conductive rubber buttons are one of the many electronic product buttons, and their main function is to achieve conductive functions through conductive rubber buttons. When the conductive rubber button is pressed, the conductive rubber under the button can achieve electrical connection with the contacts below. When the conductive silicone key is released, the conductive rubber under the key bounces up and does not communicate with the contacts below. Conductive rubber buttons are mainly used for dictionary keys, remote control keys, POS machine keys, scanner keys, password keys, keyboard keys, single point keys, etc. So how does conductive rubber buttons achieve conductivity, that is, what is the conductive principle of conductive silicone buttons? It's actually very simple: the conductive material of silicone rubber buttons is a black conductive adhesive, and by adding conductive fillers to the conductive adhesive, the conductive effect can be achieved. Diameter, length, width and height, key stroke distance, pressure requirements, product hardness, color, conductivity requirements, etc. When purchasing conductive silicone keys, the characteristics of silicone products should be considered. The production process of conductive rubber buttons: 1. First, ask the customer to provide us with 3D drawings or samples of the product style to be customized, and then design and make drawings based on the information on the drawings or samples, usually using flat drawing software; 2. After designing the production drawings, the mold can be opened. Professional mold masters use CNC machine tools to design and program, and then turn on the machine. If it is a complex product, it needs to be demolded using spark copper workers. So the technical content is relatively high, and the mold opening time is relatively long. After the mold is made, production is easier; 3. The materials used for making conductive rubber buttons are environmentally friendly silicone and rubber materials, with a general hardness between 29 and 69; 4. After the mold production is completed, it can be installed on a professional production machine to start construction; 5. After the finished product is produced, strict quality inspection should be carried out, and any non-conforming products should be scrapped; 6. Generally, the conductive rubber buttons produced will have residual burrs, so the products at this time need to be treated by employees; 7. After completing the post processing, quality testing should also be conducted to see if there are any non-conforming products. After the inspection is completed, packaging can be carried out according to customer requirements. The principle of conductive rubber buttons is the same as ordinary buttons, that is, after pressing a button, the two contacts are connected. The difference is that ordinary buttons are soldered onto the solder pad, while conductive rubber buttons are fixed to the product casing. Conductive silicone buttons are not only used in TV remote controls, but also in many other consumer electronics, medical products, handheld instruments and industrial control products.
