I would not call them rags but would call them lint free wipes. They are 100% cotton twill wipes. That means they won't leave a residue even when wiping thruhole components, you would think they would tear but they don't. Most high quality jeans are

-Are these lint-free rags ESD-protected = yes, must be. I left that out thanks! -How do these lint-free rags remove the flux that seeps under components = no matter its a no-clean material and we are removing for esthestics only. -Have you considered

Hi, My name is Branden Spencer and I am a jr. engineer at TTM technologies. We are currently having and issue with our wave solder process. We are getting what looks like either solder dross or voiding in our solder joints (through hole and SMT). We

We can make the numbers come-out looking impressive either way. In real life, our sense is: fully burdened, it is a little less expensive to use a contractor. Now, we're only talking costs. Non-cost factors often end-up putting on the brakes and t

Hi Deni, X-ray will not be able to see through Power and Grn planes. Your only way to find out is: 1) ask your board supplier to supply stack up used. 2) surface grind layer by layer to validate if it is correct stack up. What is making you think

Hi Mabdalla, Attached is my VIOS file. The board dimension in your file is 285.75(L) x 215.90(W) I do not see the board thickness in your file. The dimension in my file is 192.7(L) x 153.67(W) x 1.8(T) Hope this info would help you a little.

Hi, Looking for views and some opinions on the best systems to use to clean pads (particularly BGA) prior to carrying out replacement of parts. I'm thinking of vacuum type desoldering systems. Obviously braid is an option which we currently use, but

I think the oxidation on the pad happens easily but do not on Au plated pad.The reason may be caused by improper cleaning or Au plating thickness in plating process. But,before suspecting the pcb board, you need to check your process or used material

Hello Does somebody of you have some experiences with ultrasonic detectors in SMT-Production? Is it possible to test quality of solder joints by using a ultrasonic detector similar to non destrucitve crack inspection tests? Is there a manufacturer fo

After checking some of our stencil data for the correct aspect ratio I found that a few are wrong. I would like to change them from 5mil thk to 4mil thk but do not know how much paste volume I need to keep. We are using 0201,0402, and BGA with 0.80 p
