AOI false fail PPM

Electronics Forum | Thu Aug 07 22:56:50 EDT 2008 | dlocampo

First all, you must define the specific defects that you wanted to screen out by your AOI system based on its capability, so you can allocate the undetected defects on your other means of inspection methodology. Then optimize your AOI inspection para

Stencil design (maybe old) question...

Electronics Forum | Thu Feb 05 02:34:05 EST 2009 | sachu_70

Hi Manuel, most passives are chip components. These tend to self-center/align during the reflow process. However, you need to ensure that there is a uniform balanced solder paste deposit. I had tried few such ovals in earlier stencil designs and resu

Thanks for you suggestions, guys. davef, I am gonna get with my PCB suppliers and talk to them about copper balancing and checking the Tg of the materials they use. SC, I am working towards designing wave pallets for my boards and try your suggesti

There are some good suggestions here...reflow pallets, and copper balancing. We would also suggest verifying that your problem is not caused by moisture. How much time passed between first side and second side reflow, and how humid is the environme

PCB Solderability

Electronics Forum | Tue Oct 05 22:33:24 EDT 2010 | Mag10

Is there anyone performs solderability evaluation on PCB as a part of receiving acceptance criteria. It's costly to perform any form of physical evaluation whether simple as dip and look or wetting force balance. How do you have control in place to a

What is the best Low Volume Reflow System

Electronics Forum | Thu Feb 07 16:37:02 EST 2013 | jasowiii

This is good information but I had hoped to get specific manufacture and/or model infomation on equipment that someone has experience with. For instance I bought a Husqvarna model 455 (rancher) chain saw last year. I cut through 3 cords of fire wood

If my memory is correct.... You need to add program for top and bottom into the production planner tool , Ie 100 x Top, next job 100 x Bottom Then can run a cluster line balance Then can export out HLC/Machine Split files... Have a play with Prod

Removing Treiber Wave Soldering Machine Chains

Electronics Forum | Fri Jun 17 17:33:30 EDT 2016 | winterair

The machine has been giving me trouble as the components are frequently lifted off the board and falling off as it goes through the conveyor. I am trying to remove the conveyor chains hoping to re-balance them. Is there a way to remove them and adjus

SMT part placement delay

Electronics Forum | Thu Aug 24 18:28:41 EDT 2017 | tey422

dwl is right. You just have to spend some time to play with all the ones that causing the most delay. I would say the timing for X & Y axis try to set to max speed first (as long as not drops before placing). Then, slowly increase the Z speed until
