Flux Fluxing applciation standards

Electronics Forum | Wed Jul 29 12:14:30 EDT 2015 | davef

There is no current standard for the amount of flux that should be applied to a board. Current standards focus on what the result of a process should be, not how the process should be performed. So, the standard tells you that you need a procedure de

Adaptable PCB support systems for use in pick and place machines?

Electronics Forum | Tue Aug 04 14:56:27 EDT 2015 | sarason

Adding to my previous message this could be solved fairly easily for the general case with a jig made from 3.2 - 4mm aluminium aircraft grade plate. you would machine the bottom side edges to give a 1.6 mm thickness, then machine the top side to leav

DPAK's falling off pad during reflow

Electronics Forum | Tue Aug 11 09:52:53 EDT 2015 | rgduval

I assume that these parts are falling off during second-side reflow? The easy solution, of course, is to not build high-mass components on first-side reflow. If this isn't practical, however, you can try using epoxy/glue under the component. We'

Problem is solved! There wasn't voltage on motor inputs (only 5-10V AC) when the motor connected correctly, but was ~210V AC without motor. Firstly, I exchanged the motor speed control relay (Panasonic G-series type), but the result was same. (the a

What's the best company for low volume, quick turn around PCB assembly?

Electronics Forum | Mon Nov 02 10:43:13 EST 2015 | dyoungquist

As for cost, that will depend on several things.... -Turn key or consignment? -Diversity of components? -Total quantity of components to be loaded? -Single or double sided SMT? -Individual boards or are they panelized? -No clean or water soluble flu
