Remember as well, the Mirtec machines have laser technology being used to check for coplanarity/lifted lead issues. Having this capability will reduce false calls in most circumstances.

I have seen an issue that escapes our ICT and functional testing or operates in an intermitent fashion. The lead is slightly separated from the PCB with a fully formed solder joint behind it at the heel an toe. The joint apears to have started to tra

Dave Thanks for the input. The thermocouple read 244 on the pad of the socket. We actually found after extensive investigation that it is the coplanarity of the leads. We were shipped a bad batch of sockets form the manufacture. Go figure!!1

Problem: A SMT fine pitch or BGA component needs to be baked due to MS concerns and is needed in a hurry. In some cases the packaging will not allow a high temp/short duration bake. Production will not allow a low temp/long duration bake. If the part

Remeber Do not use any probes or fixtures to hold the lead down while soldering or rework .....this is a bad idea. I would remove the component and replace or gently push the lead back into coplanarity and resolder. This all can be done at most rewor

| | Does any one have any idea which is usualy more expensive, to get components on Reels or in Trays ( I mean large components ofcourse). | | What is price diffrence percentage ? | | | | practicaly, is one method is prefered to the other? | | | |

Jeff: Two things come to mind (if that's not stretching things too much ...): 1 You've got something unsolderable and not removeable with fluxes is on your component leads (or you don't have enough stomp in your flux). Do the leads that don't sold

| Yes l know this problem keeps cropping up on the forum but l've missed some of the follow-ups. | | Our problem is that the lifting only occurs on 3% of production so actually detecting an improvement is difficult. We're actually having to inspect

| Looking for advise on placing 56 pin TSOP from tape and reel. Been told that placing TSOP's greater than 32 pin from tape and reel can cause significant reliability problems. True? False? Comments? Any reference literature available? | | Hi

Hello Nagesh, Do yourself a favor, check out MIRTEC's MV-7 system. I purchased one of these machines with the Intelli-Scan laser option. This is a secondary laser inspection system that allows you to test for coplanarity of leaded and non-leaded de
