Using this service you can get 5 double sided PCB boards, up to 250mm x 250mm made by a professional fabrication house, with a green solder mask and white silk screen.

The boards will be made at the same factory where we get our prototype boards made, so we know the quality is high, and all boards are 100% E-Tested at the factory.


These Prototype Boards are finished with HASL.


Please send a ZIP file containing the following files to :

Top layer: pcbname.GTL
Bottom layer: pcbname.GBL
Solder Stop Mask top: pcbname.GTS

You may panelize your design (or multi designs) on the 250x250 board, BUT these will not be routed out, you will have to cut them yourself.


This service will take around 15 working days.


If you require larger boards, please contact us through the 'contact us' page or email


Please note : A manufacturing number will be added to the silk screen - this is so we can find your boards from the factory.

                      This is a PROTOTYPING service - the finish may not be up to a production standard (but they will be fully functional) - if you require production boards

                      please contact us at with your requirements and we will get a quotation for you.
