Knowledge of Electroplating Solutions That Affect Electroplating Quality
The main salt refers to the salt in the plating solution that can deposit the required coating metal on the cathode, used to provide metal ions. The concentration of main salt in the plating solution must be within an appropriate range. Increasing or decreasing the concentration of main salt, while other conditions remain unchanged, will have an impact on the electrodeposition process and the final coating structure.More -

The Difference Between Light Release Force and Heavy Release Force of Release Film
Firstly, there is an understanding of the definitions of the two. Release force, also known as release degree, refers to the degree of release of release paper. There is no absolute value at this point, and it depends on the formula of each manufacturer. Depending on the amount of oil applied, it can be divided into light, medium, and heavy release forces. The peel strength refers to whether the release paper (film) is easy to peel off from the attached product, which is determined through strict testing.More -

Test Standard for Release Force of Release Film
Test steps: Place the TESA7475 adhesive surface downwards and lightly press the adhesive strip onto the clean test board. Use a pressure roller to press back and forth at a speed of approximately 10mm/second twice, making the adhesive surface in close contact with the test board. (The release film needs to be pulled or fixed on the test board.) After the test strip is applied properly, it should be left for 20 minutes before testing. If permanent peeling force needs to be tested, it needs to be left for 24 hours. Debug the stripping angle to 180 °, set the speed to 300mm/min, and run the test on startup.More -

Application Fields and Uses of Release Film Industry
High temperature resistant release film: it is made of polyimide film as the base material, coated with imported high temperature resistant silicone pressure sensitive adhesive, and then coated with polyester release film. Tape has excellent high temperature resistance, electrical insulation, and chemical resistance; And it is non-toxic, odorless, and harmless to the human body and environment, due to its extremely low release force.More -

Buffer Pads for Circuit Board Lamination
The circuit board pressure transmission and pressing cushion pad is developed and produced for the ultra-high temperature press currently used in the PCB industry. When the circuit board pressing temperature exceeds 260 ℃, the general Kraft paper, cushion pad and other auxiliary materials can no longer meet the pressing demand of high temperature, and fiber materials with higher temperature resistance must be used. At present, this RCX-K25 cushion has excellent temperature resistance and can meet the requirements of ultra-high temperature pressing.More -

What Are the Uses of Release Film Classification?
Release film refers to a thin film that, under limited conditions, does not produce stickiness or slight stickiness when in contact with a specific material, and can distinguish the surface of the film. 1、 The use and characteristics of silicone oil release film are selected with good PET substrate, which has uniform and stable release force, non static/single (double) anti static, and diverse thickness and color. It is mainly used for non drying adhesive tape, double-sided adhesive tape, precision material die-cutting, etc. The silicone oil release film used in the graphite industry has uniform and stable release force, ultra-light/overweight release force, thickness, and multiple colors. According to customer requirements, the release force is 300-400g, which can also be used as an anti-static layer,More
