IPC-7525 tells you how to make stencil apertures for BGA IPC-7095 tells you how much should be the paste volume in order to get a reliable BGA solder joint. How are your PCB finisced? (HASL, ENIG, OSP, etc?) In case of not HASL, it could be necessa

We are currently completely building lead based assemblies. We are going to start doing our homework based on Management request. I have a pretty strange question that I was asked but really did not have an answer to. Can a Lead-Free assembly have a

In order to get started in understanding the basics of wave soldering, read this http://www.ami.ac.uk/courses/topics/0225_wave/index.html Many board assemblers have replaced wave solder machines with selective soldering machines. * Often, modern bo

Dear Anshang38, I actually don't have a profiler in order to get a new profile. I adjusted the machine once a coulpe years ago and did all regular maintenance and cleaning and it kept working fine until some weeks ago. I've changed all the flux and

The size of a feeder is determined by the width of the carrier tape the components come in. i.e. If you measure the width of the tape with a precision ruler or calipers that measurement will be the feeder size. Also, when you order parts the tape siz

Hi, Does anyone know of some good software for managing component consumption in manufacturing and keeping track of what products use what components, and the consumption rates over time. This lets us forward plan component orders for future product

I'm curious why you ask this question even though I really don't know whether there is such smt assembly facility in HK. Maybe you think there is 17% VAT in the components to China outside from China mainland, but there is no tax in HK. I have to say

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/,

I am running a board that is .062" thick and has components that over hang the edge of the board by .090". I have bottom side smt components (chip caps and resistors only) and use the turbulent wave to help solder the components. The problem I am h

Hello everyone. I am new to the forum so I am sorry if this has been asked before. Does anyone have any suggestions for counting partial reels and cut tape? We are a distributor and for our ecommerce PDC we keep having quantity issues. Currently, we
