Has anyone had success utilizing the lifted lead/ height checker feature on a Mirtec MV-7L. We recently had two separate events where the machine did not detect a lifted lead using the ic/bridge inspector. The soldering results came back with out def

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

Both questions will depend upon the IC specifications. Check the manufacturers recommendations for temperature specification, as well as reflow profiling. As a general rule, we don't like to rework a component more than 2 times after initial reflow

are the ics jumping in the tray. if not seated correctly the lead lift at pickup. mostly lift lead causing by handling.

we have observed a Field claim in ECU where root cause is Lead lift found in one of the IC. What could be the possible reason for lead lift and how to avoid the same in future. QFP is the Type 1.Checked the Part Library(3-D Check Refernece no.-23

Dear Abhishek, I too got the opportunity to investigate this defect Lift lead for SOT. Lead lift in IC, and SOT can occur due to various reasons. Here are some possible reasons for lead lift and ways to avoid them: During the assembly process, mecha

The general control on QFP fine-pitch coplanarity is +3mils. suggest to look at the re-use of thrown out component from SMT machine. If the component pack in std pack, then most probably the lifted is due to processing, not incoming as the packaging

I�m interested in the F1 model, due to the possibility of this system to be configured with 1 top camera and 4 side. We are manufacturing 0402 and 0.4mm fine pitch Lead Free, and our PCB�s quality is not very good. With just one camera are you able t

We have recently faced lifted lead problem that happened on our 20 mil pitch QFP. We have infact pushed it back to the incoming quality, but still I have a few questions to bring up : 1) what is the typical coplanarity tolerance that ICs' manufactur
