Immersion Silver Printed Circuit Boards
Immersion silver is the final surface finish on our printed circuit boards, and is available for all pcb's at North Tech Services. The immersion silver process leaves a thin, highly wettable layer on the all exposed pads which gives excellent soldering performance. Immersion silver is particular beneficial for pcb's which have surface mount components, require lead free compliance or a high performance layer which provides excellent manufacturing yields. For more information please read the immersion silver product brochure and immersion silver frequently asked questions.

Immersion Silver Frequently Asked Questions

Single Sided Printed Circuit Boards
Our single sided circuit boards are available on a variety of FR4 laminates ranging from 1.6mm with a copper cladding of 35 micron or 70 micron. We also stock 0.8mm thick material for lightweight and space saving applications. Should you require solder mask on your printed circuit boards, our single sided boards are SMOBC (solder mask over bare copper) and can have a roller tin/lead finish or immersion silver finish. Our normal turn around time for a single sided printed circuit board with solder mask and top silkscreen is approximately 4-5 working days. For a plain single sided PCB the turn around time is 3-4 working days.

Double Sided Printed Circuit Boards

Our double sided printed circuit boards are processed in the same manner as our single sided printed circuit board. We have FR4 1.6mm material with 35 micron or 70 micron available or FR4 1.0mm material.

Double Sided Through Hole Plated Printed Circuit Boards

Our normal delivery times for THP prototypes with solder mask and top silkscreen is approximately 5 working days. Our THP boards are available on FR4 1.6mm and 1.0mm with 35 micron being the standard. 70 Micron printed circuit boards are available on request. When you order your THP printed circuit boards you can specifiy to have immersion silver as the final finish, this will leave only immersion silver on the exposed pads and solder mask over bare copper (SMOBC) which will give great performance with reflow ovens and wave soldering machines.

Solder Masks and Silkscreens
Solder mask inks are available in green (standard), blue, white and black. Silkscreen marking ink is available in white (standard for best contrast) and black. Solder masks and silkscreens are optional and should you require a more cost effective printed circuit board, they can be omitted from your order.

Specialized Ink Coatings

Should your design require a black coating ink or carbon ink pads , please enquire before submitting your order.


V-scored Panels

We can supply PCB's in a panel which are v-scored. These PCB's can be separated with a PCB Separator once fully assembled.The smallest panel that can be successfully v-scored measures 60mm x 60mm. Panel size can vary depending on your needs or the initial quantity ordered.
