Product name:
Industrial control board
Low cost pcb fabrication
Characteristic:
1, the board design integration is very high;
2, the need to use composite surface treatment method, gold finger plating hard gold 30 uinch;
3, gold finger position plate thickness tolerance 1.6mm+/-0.10mm, it is recommended that customers in the design of the gold finger corresponding to the inner line of the copper block, in order to facilitate the plate thickness tolerance control.
