What is the use of gold finger tape? What are the quality requirements?

　　Golden Finger TapeWhat is the use? What are the quality requirements? The gold finger tape is based on polyimide film and coated with high temperature resistant silica gel. It has the characteristics of environmental protection, high temperature resistance, corrosion resistance, strong adhesion, good shearing performance, no residual rubber tearing, easy punching and die cutting. Temperature resistance is generally between 120 and 260 degrees.

Gold finger tape is generally yellow brown or golden yellow, with a width of 10mm, 15mm, 20mm, 25mm, etc. Length: 33m/roll. And its coating accuracy can reach 2.5um, there will be no scratches, wire drawing and other phenomena, should be widely used in many industries.

Gold finger tape is mainly used in wave wax and reflow gold finger protection, paint, paint leather processing, paint masking and electronic component manufacturing process, printed circuit board and high temperature processing masking, lithium battery manufacturing, surface mount technology, transformer manufacturing and other industries. Gold finger tape is suitable for manufacturing electronic products such as coils, winding insulation, capacitors, etc. Gold finger tape is also commonly used for winding coils, transformer motors, capacitors and wires, fixing the tabs of lithium batteries, protecting the heating process of electronic products and various high-temperature shielding protection.

The application of gold finger tape is as follows:

1. Electronic protection sticker

The tape is especially suitable for SMT temperature protection, electronic switches, PCB boards, gold fingers to protect electronic transformers and other electronic components that require high temperature and moisture resistance.

2. Electronic circuit board

Gold finger tape is usually used for wave soldering shielding of electronic circuit boards to protect gold fingers and electrical insulation, motor insulation, and fixing of positive and negative ears of lithium batteries.

3. Insulation of electronic products

The tape can be used for insulation winding of H-class motor and transformer coils, winding and fixing of high-temperature coil ends, and bonding insulation functions under high-temperature conditions such as thermal resistance protection.

Quality requirements of 2. gold finger tape

1. The adhesive tape should be durable, and it will not be able to dry after a period of time;

2. When the tape is torn off, it should be able to be torn off as a whole;

3. After the peeling is completed, the gold finger tape can not have residual glue or photographic phenomenon;

4. After the tape is bonded for a long time, there is no bubble floating or warping;

5. The tape shall be weather-resistant when used outdoors;

6. gold finger tape can not have crystal point.

Gold finger tape has high and low temperature resistance, acid and alkali resistance, electrical insulation, radiation resistance and other properties. Strong adhesion, soft, no residual glue tear. The advantage of the golden finger tape is that when the golden finger tape is torn off after use, the surface of the protected object will not produce residual glue.
