I always look for a toe fillet if the design allows you to. Many times the pad design is close or exactly the size of the leads which makes people to touch it up right away. I told them hundred times not to but...Luckily I have 3D x-ray and I can tel

We are looking for a inspection system to check the positioning of a component over a PCB. We need it positioned both in X Y directions and height above PCB (it is a TH component) to be within certain limits. PLS advise can this be achived by AOI. Wh

Try TESTRONICS 505 series. Ask for literature on this subject. They are a very responsive company.

Good job clarifying things. So, your MELF are just rolling off the pads. So much for the rocket scientist that talked you into those �V� shaped apertures, eh? [Or taking it the other way: Wow, just think how bad it would be if they weren�t worki

What kind of AOI machine are you using? Some OEMs seem to not understand that we want to also check for correct parts with AOI not just absence/presence and solder joints. But markings are an issue. I remember when 0805 caps had markings.

Hi Dave Interesting points. If I understand you correctly 1. about 2% of part numbers have a moisture problem 2. Packaging frequently comes in with expired dates on them. This seems hard to believe you would accept them. 3. To really solve the

Emmanuel: You have choices to prevent the solder paste from flowing to the second side during reflow: 1 Have your board fabricator plug the vias. 2 Put a temporary solder mask on the secondary side vias. 3 Have your designer relay-out the vias unde

I do have access to an X-ray but it is only 2-D and it just appears as a black solder joint, not to impressive.. The main question though if it is a reowked solder joint does it still need to show wetting on the lead or can it be covered with solder

Do you have access to an x-ray system? If so you can determine if the solder wetting to the lead along it's length meets the criteria set out in IPC-610. Pete B.
