In the production process of the circuit board, we often see that the circuit board is covered with copper wire and the surface is covered with glue, but we rarely know what role they have on the circuit board, then we will understand what they do.
The significance of applying copper on the circuit board is to reduce the ground impedance, improve the anti-interference ability, reduce the voltage drop, improve the power efficiency, connect with the ground wire, reduce the loop area, greatly strengthen the role of the circuit board components closely connected, and improve the functionality of the product. The coating on the circuit board is a waterproof insulating adhesive, which can form a protective layer on the circuit board after coating, resist various adverse factors in the harsh environment, avoid any adverse effects on the circuit board, and can play a role in moisture-proof, mildew proof, salt spray prevention, etc., effectively improve the reliability of the electronic circuit board. It also has excellent flame retardant performance and high and low temperature resistance, even if it is subjected to cold and thermal shock between -60 ° C and 200 ° C, it can still maintain elasticity, and can maintain low stress in extremely harsh working environments; The flame retardant level reaches UL94V-0, effectively improving the safety factor of the circuit board, and the solvent-free formula is used, without any harm to the human body, health and environmental protection, and it fully complies with the requirements of RoHS and Reach directives.
In the circuit board, they are indispensable, have a very important position, and are also one of the most reliable products.
