Using isopropanol with DI water for rinsing after washing boards

Electronics Forum | Fri Nov 11 13:52:05 EST 2011 | SheanDalton

What is the size of the low standoff components you find trace wash effluent? and, what is the gap from the board to the underside of the component? If your component has a very low standoff, and/or, a wide footprint, you may want to consider findi

I think I've got it. 1. Black flat connectors are for the nozzle changers, and whether or not the tab is pushed in or out (depending on whether they are placed in front of one of the blocks on the feeder base doesn't matter at all, the blocks are th

Bobpan, It's been a while, and I haven't really had a need for this (simple boards, with larger components), but now I'm back to a board that needs this. I only have options for HOLD, PASS or VISION under transport in the Sequence Programming.

Bobpan, Thanks for the reply. I have been using Tep Vision, I'll see whether I was using GOTO 1 or 0, it may have been 0. I am running from central controller, and am doing a download database from the database utilities when making changes on

Hello Sergey, I have used Kirsten Modula Wave with ADL (anti dross liquid) option. We have had the same expectation like you: less dross and lower operation cost due to no inert gas is required. That is achieved, the dross generation was modest and t

some things to consider, Is there flux on the board. are there finger prints on the tops of parts. Is the board warped at the V score from reflow Is the board shifting in the machine during inspection. These are the issues we have had with our mir

I have a problem setting up the LAE on my Quad 4c. I set it up for 0805, and it seems to work, although it rejects a lot of parts, at least it places "most" of them. I tried setting up on a soic14, and could not get even one to pass. I believe I h

More lube on the O-Rings caused lots of problems. Nozzles would drop downward at times. So I pulled everything out and started from scratch. Testing 3 new Z-Rods, 4 used Z-Rods in good shape (replaced the O-Rings) and around 20 nozzles - the proces
