Hi, I am an engineer based in Scotland, but have some IC's sitting with a company in the Boston area, that need checked for coplanarity. Does anybody know of a company/ lab with a lead inspection machine that they could be sent to? Regards, Dave.

dave, you are right on. a blow torch isn't needed to light a fire. a small coplanar aluminum block works extremely well. my dept fixes thousands of fine pitch parts to to less than 4 mils from low lead to high lead every month. all we use is a sm

LarryK, You might want to talk with: Fancort Industries, Booth #2630 31 Fairfield Place West Caldwell, NJ 07006 973-575-0610 www.fancort.com MLCS-1 Manual Lead Conditioning System. It is a bench top, hand operated machine to correct deformed lea

Jerry, I know I'm off target, but I don't care. Three things: 1 We don't see the level of malformed leads that would pay-back a $30k investment in 10 years. (Of course, we haven't talked about volume, but you can't have very much volume, can you??

When you say "dropping" I assume you mean "rejecting" them because co-planarity is outside the tolerance you have set and the machine is putting them on the reject belt or tray as the case may be. I worked for a CM with an MPA-G3. One customer suppl

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

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.

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

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
