Hi Steve, I don't have any experience with CP2's. Sorry .. hazarding a guess though... if they use the analog servo amps like they do in the CP4's, they had a bunch of trimmer pots on them. There is a procedure to zero them using the mecca check mod

Hi All, I have designed 4 Layer PCB with one 28 pin QFN PKG. I have got complaint from Production that the pads which connected to thermal pads (gnd) thru trace is bridging with solder and because of this bridge, pins are not getting soldered prope

In my experience, the best way to do a lifted lead inspection on a QFP is by laser height measurement. It is very difficult to consistently catch a lifted lead with only a top down camera. As you say, too many false calls, and still some escapes.

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

Hi All, Is there any way to use ROHS6/6 [Non-leaded] BGA device in Non-ROHS reflow [240 Deg C] temp. environment. I need to do this because Leaded [ROHS5/6] device I was using is obsolete and Non-leaded[ROHS6/6] drop-in-replacement part is availab

Has anyone had any luck programming using the side cameras to inspect for defects on the sides of chip components? We recently had an escape of a damaged chip capacitor that was impossible to see from the top camera but was clearly visible with the

Hi SMT World, I am facing a technical challenge related to an SOIC 14lds with thermal pad on it's belly that needs to be soldered onto PCB, together with leads. It is a 50 per board, expected 80% solder load on every one. We have some units without

Hello everyone, Talking to my boss today I was able to determine what we're really looking for in terms of reflow soldering. The company is not looking to do a volume run; we're trying to solder chips for prototype boards, which are currently done w
