The best method i have for the few lifted/bent lead issues we have is i use a ic/bridge inspector with all its default options to check for bridges and solder at the tip. then i add a solder inspector but this time accrost all pins at the downslope o

Has anybody else out there had problems with SMT connectors with plastic locating pins lifting up during the reflow process? We've had several instances with several differant types of SMT connectors lifting up during the reflow process. We've even g

Yes it is possible to detect lifted leads with top view camera's. The camera's must be coupled with software that utilizes algorithm programs. MVP - Machine Vision Products out of Carlsbad, California uses algorithms in their software. Most AOI co

Reese is right. We use algorithm our AOI but the make it find liftead lead on qfp or such... it took me all day to set program and even then some defects pass so that is why Im asking..

Hi We have a problem here in the company with AOI system, most of the problem is lifted lead on qfp components.We are using SAKI BF-planet-x. Most of the defects like mising components 603 or 402 are no problem but if it comes to lifted lead even

Hello Patejl, Many AOI machines have issues with lifted leads. I recall SAKI failed to catch lifted leads on my test PCB when I evaluated them. If you are looking for replacement equipment, check out MIRTEC. We now have four of these systems confi

I checked with MVP after Reese's comment, they use special color lighting in addition and have many customers detecting lifted leads successfully. It doesn't really matter unless your looking for a better AOI system/supplier. Hopefully your equip

Thanks for your feedback, both of you. But my problem is that we have high mix and low volume its obout 50-200 pieces. And we also have manual paste priter so the solder on the pad look always diferent. I believe that there is the problem but I cano

It is possible to infer that the lead is lifted based on the toe fillet appearance, but it's not as reliable as say a laser or xray inspection. This is usually done by varying the light source location and or color and looking at the images resultin

Hello Pvasquez Well that is not a good news but it is what I thought. Lets see what will say our headquarters.Could you send me some more information or materials obout mirtec machines so I can present it to our company. Thanks
