I'm working on a small design that can be duplicated twice on a single MiniBoard, that way I can get three boards and cut them into six smaller PCBs. What's...
I'd be careful in cutting the board if it has internal ground and power planes. It's fairly easy to cause shorts when you use a dirty method of cutting with...

... Nay, a bandsaw! It is often helpful to place a series of vias along the "cut line". On a double-sided board (as opposed to 4 layer) you may be able to just...
Years ago, I worked in an electronics factory and was in charge of making the single sided PCB's. The process is quite different today, but back then, we...
Harbor Freight sells a small table-top table saw for under $50. I use mine to split boards (the last one was 6-up on a mini-board order of double-sided ...
I have just cut a miniboard. I had been using Xact knife and Xact precise saw before, but this time I used Dremel and cutting wheel (No.409). It was much...

I am about to attempt to create a proto board with the $51 deal. I'm still wondering what is the rule of thumb of how much bigger to make the holes, knowing...
Okay, i see now that I asked this question before and it was answered. Basically simple arithmetic. For the hole size, take the stackup of the tolerances. Now...
... I missed the earlier reply ... what do you mean by "take the stackup of tolerances" ?? Also, I'll be curious to find out what you think of the services and...
Hey ya'll... is there any difference in the footprints of QFP vs TQFP? I've got some TQFP ICs I'd like to use... but the only component that's even close in...

First I have to tell everyone I am not an engineer or even a tech, I am a hobbyist and I have had some sucess in making my own boards with Express PCB. I want...
Hi all, I just wanted to pass along my recent conversation with Express PCB. I went to order a set of .gbr files for a recent project that I had them prototype...
That's good to know. It can be a hassle of you need a stencil for SMT. What do you use for schematic capture? And where are you sending your FreePCB Gerbers? ...

Huseyin I think that is the answer, I tried making less circiuts and it stays the correct size. I am going to test untill I find out what the limit is and stay...
Is there a down load available with extra components for ExpressPCB or a down load of custom components to add to this program and if so where do I find it?...
