Golden Triangle Group Ltd. can provide below different solder mask colors for PCB to our customers. Green, blue, white, red, black, Yellow Orange, Purple, brown, gray, Transparent and so on.    Customer can use their prefered soldermask color on their products.

GT keeps on provide Printed circuit boards to one of our customers Located in Western Coast with hard gold plating 17’’ and depth routing control on the boards’ center over 2 years; Occasionally, on one official video technological meeting with customer, GT showed customer with another different type of sample with Pin inserting on the PCB boards, which brought GT a new chance and serials orders---new designed with Pins assembled on the bottom side!
