Hello,my question as below: 1. If the component is black color but the color of PCB is dark green. It seem no different in color between it. Any suitable algorithm can be used on it? 2. Algorithm Mem1-Mem2 make many false error and affect the First P

Relay failures

Electronics Forum | Tue Jul 29 14:25:20 EDT 2014 | kenkay

We have been struggling for a while with some through hole sealed mechanical relays that fail at test after they have been sitting a while. They will initially pass test, but seem to fail if they sit for a few days. We made sure our wave process was

Can anyone tell me that between Mirtek & Kohyoung which AOI machine will be better and why?

Electronics Forum | Thu Feb 12 21:14:37 EST 2015 | kahrpr

They are both very good machines however Kohyoung will give you better first pass results meaning a lot less false calls and when you run the first board after initial programming you have to fix very few things. However the cost is a lot more. This

SMT line validation if AOI available

Electronics Forum | Wed May 27 18:53:26 EDT 2015 | ldempsey

An AOI is only as good as the templates taught into it. How would you like to build 1000 boards and have them pass your in-line AOI, only to find out later, there was an incorrect reel loaded? A slightly different shade of light brown cap, but st

SMEMA Conveyor into Reflow Oven? How to handle end of line signal.

Electronics Forum | Tue Dec 29 11:38:40 EST 2015 | g2garyg2

Hi Tom If the DYNAPACE has SMEMA out all you need to do is place a two wire jumper into pins 3&4 or 1&2 depending upon DYNAPACE's SMEMA configuration. This will by-pass a Release signal and feed PCBs into the oven.

AOI Machine Daily Verification

What exactly are you looking to verify? Following the manufactures recommended schedule for calibration should be enough. Another option is many AOIs have an option to run a bare board, when doing this it will invert what it's looking for, so every

How thick are their requirements? A barrier can be made using peelable latex. That would then require manual or automatic dispense of latex to create a dam. Then you should be able to use an automated dispense system with a large orifice and flood

Hello, The machine measures the part using the laser on the head after picking it up. It then passes or fails it by comparing it to the part size and tolerance for the pickup in the laser extents. You can see this in central controller under laser ex
