PCB Design

This shows a small piece of a Printed Circuit board with surface mount, mulitlayer and BGA. If you want to see the whole image, it can be downloaded here but it is about a half a megabyte. It requires the Adobe Reader which may be downloaded free of charge.

Most printed circuit boards have many layers; more than just the obvious ones. For example a "four layer" board can have the following structure:-

Top Solder Paste
Top Silk Screen
Top Solder Mask
Top Layer
Internal Plane 1
Internal Plane 2
Bottom Layer
Bottom Solder Mask
Bottom Silk Screen
Bottom Solder Paste

In addition, other layers can be created for example Gold Plated (Au) patterns for switches and many other specialty items.

MacPherson & Associate has been designing Printed Circuit Boards since 1985.

We offer schematic capture, PCB design and layout, and the production of Gerbers™ from the layout database.

If you have an old board with no documentation we can perform reverse engineering to provide you with a complete set of schematics, database and Gerbers™

We can fabricate the board for you and also assemble the board to give you a finished product.
