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

Hi Dave, yes messy, that�s the result of trying to use the newest chips available, getting the first shot (prototype chips) and building a couple of hundred boards and than detecting that the protos do not what they are supposed to do.As our market 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

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

Possible, but difficult. What algorithm programs are you referring to? Mirtec and YesTech both utilize algorithms in their respective software. The algorithm is simply a series of instructions to perform the inspection. In this case, rules-based,

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

Hi all, a lifted lead (FP 0,5mm pitch) with a wire soldered to it needs proper protection against tear off. What kind of coating is appropriate, should be dispensable and fast drying. Thanks in advance Wolfgang

I have used Loctite, RTV3145, or Tak-Pak to secure the wire. As John said, the wire is usually secured to the board near the lifted lead, and usually at 1/4 inch intervals along the way. Brian W.

Hello Wolfgang Try looking in the process guides section of Circuit Technologies web site. Their recomendation is to bond the jumper wire to the board within 6mm of the lead with hot melt glue, cyanoacrylic glue or adhesive dots. John Thorup
