We learned how the inner core of a 4 layer PCB is processed prior to adding the outside layers in our last post. In this post we will take about the next part of our “sandwich” construction – but first, let’s start with a brief introduction of foil lamination. Foil Lamination There are a variety of ways that foil lamination is used as well as a variety of materials that Read More..

We like to hear from our customers on how we are doing. So we setup this comment page so we can hear the good and the not so good if needed of how we are meeting your expectations. Please take a minute and let us know in the comment box below.  

I just wanted to thank Angela Alexander from Iconnect007.com for attending our workshop and doing this write up.  Angela also took the pictures you see here as well.   Recently I was invited to Bay Area Circuits for an evening of Pizza, Pop, and PCBs. The event was organized by Peter Brissette, Marketing Manager at Bay Area Circuits in Redwood City, CA. The seminar has long been a dream of Read More..

In our last post we talked about the basic material used to start the PCB manufacturing process. If we were doing a double sided board it would actually be going into drill at this part of the process. We will get to that eventually. What we are going to do is walk through the multilayer process which is a different process initially. We will pick up at drill and the Read More..

This is the first in a series of articles that will explain what is involved in the Printed Circuit Board (PCB) manufacturing process of a double sided PCB and a multilayer PCB. This will be very high-level overview to provide someone who is not familiar with the manufacturing process the basics of how a PCB is manufactured. Those who will find this series most useful will be hobbyists, students, and Read More..

Common Problems with Gerber Files and How to Avoid Them! The reasons we want to address these common problems is to help reduce the number of errors, mistakes and time delays when manufacturing your PCB. All of these reflect in higher costs in the long run which no one needs! Obsolete File Format: There are basically two types of file formats: 274D (requires aperture list) and 274X (apertures are embedded Read More..

Gerber File Extension For those that are not familiar with the Gerber file extension designation of rs274d vs rs274x we put together some basic information to help you understand the difference and why it is important in the PCB ordering and manufacturing process. How can just a letter make such a big difference? At first glance the “d” would seem like it would be better than the “x”. After all Read More..
