Sorry for being late on the reply. Whatever you do, flux from the container or the manufacturers flux pens. Stick witht the same chemistry. Mixing chemistries, IE: different fluxes will create more problems in rework than you will see if you use the

We usually get some mask material from our board house. It cures with heat so it works really well in our applications. Be wary of the "overcoat pens" they don't seem to hold up under heat and thre solder will flow right underneath it during BGA a

Hi On the earlier AVX400's there was only one serial port. In the past one of our guys have informed me that we have used an adaptor and plugged the mouse into the LPT1 port. On the later machines there are two serial ports so you could use one of t

Thanks for the replys guys. There is infact a serial port in the back. It is COM2. I just had to plug in a standard mouse with a Serial to PS/2 converter and enable the mouse to use COM2 in the Windows control Panel. Works better than the stupid ligh

You have two options 1. Get some real solder mask form board supplier (not touchup pens) and repaint the trace and heat cure. 2. Fill the via with solder before reflowing new part, this usually works but sometimes it doesn't. We use Method 1 Russ

The problem with super glue is that is has a cyanide base that turns into a toxic gas and evaporates when heated. See IPC-7095. Via's should be fully plugged with solder mask at the fab house. If your PCB designers are not up to speed on IPC requi

-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
