IsoClad 917 High Frequency PCB on 20mil (0.508mm) Substrate with
Immersion Gold and Green Solder Mask
(Printed Circuit Boards are custom-made products, the picture and
parameters shown are just for reference)
General Description
This is a type of double sided wrap-around antenna PCB built on
20mil substrate, cladding 0.5oz copper plated to 1oz. The boards
has a size of 126mm long by 95mm wide used on intelligent helmet.
Surface finish on pads or exposed tracks is chemical gold which is
very good for SMD soldering.Green solder mask protects entire
board. They are strictly manufactured as per IPC-Class-2 standards
and 100% electrical tested. Every 30 boards are vacuum packed for
shipment.
