I checked the spec sheet and it gives pressure and no volume. The volume on one of my older Yamaha's was about 2.7 CFM. That corresponds roughly to the volume of a small 2HP compressor at your local hardware store. You can place on of these in a smal

Actually it is, open it with a nice safe text editor and in amongst all the binary crap it cannot read are a few clues. This file was created with a free PCB layout tool called PCB Artist that is given away by Advanced Circuits http://www.4pcb.com/,

Hi, 1. do not use flux-cored wire- the smell is bad and flux will evaporate anyway at the time of solder wire melting. 2. as suggested use solder bars, something like this: https://smtnet.com/company/index.cfm?fuseaction=view_company&company_id=39635

This is a similar question to https://smtnet.com/Forums/index.cfm?Thread_ID=22578 but I didn't want to steal their thread. In the recent COVID-19 events, I guess that some US companies are going to think to relocate their PCBA work from Asia / China

I have used Kapton stencils before. The only issue was they don't last nearly as well as the steel ones. For rework if Circuit medic had the stencil in stock we would buy those. If not there was a stencil shop that would make them from Kapton. I do

I am to implement PBGA, and i am looking for PCB surface finish informations. A lot of technical reports are specifing NiAu finishing because of flatness property. Because of leads shape, I though that BGA doesn't need flat pads like QFP. Is it false

Assuming agressive design rules what is the minimum distance I can get away with between the board edge and a SMT pad and between the board edge and a plated mounting hole ??? (The board is only 1"x2" and the mounting holes are 80 mil dia, 125 mil

Stu, it is good you know that there are limitations and you want everything. Wish our designers work like that. So, the limitations we impose are dictated by the rails of the insertion and dispensing machines. Normally a .150" keepout will make a s
