Well, I have not had a chance to run my experiment yet. I hope to have the wave solder machine to myself on Friday morning. I will let you know. I am hopefull from what you and the others have said that it will work and we can reduce our touch lab

I have seen BEC holes drilled wrong also. On a couple of products We run, We insert a Pem Nut. The insertion hole is too large for BEC to read. So We have the board house drill a small hole for each array, circuit. If these smaller holes are drilled

99% (there will always be that one that gets jacked somehow). Your old placement equipmment may affect this by dropped parts that get underneath the BGA, etc.. hopefully the placement accuracy will at least get the parts halfway on pad and they will

we have a HSP 4796, and have had placement issues with 0402's. If you can rule out global correction, rev'ed boards and a loose nest or a lack of support under the board. Look at placement before reflow. If alignment problems are present before oven

We also have 4796's and 4791's and have had the same issues with 0402 parts.. All the suggestions listed in the last post will help quite a bit. We found our biggest problem was the board supports due to the operators using the wrong type of pins ,

One other thing to check is your PEC camera. Universal uses a jig to calibrate this camera but you could check it using this method. 1.Run about ten 0402 parts on tape with the PEC camera off and check placement. If the placement is off change the x\

Hello my name is Jason. And I to work in electronics. I have recently had the same inquires by costumers about solder height to. Are these well-known customers like hp or micron? Cause it sounds like it to me. Who do you deal with that makes these in

Thanks Dave, From what I remember a lot of components went away from Silver Palladium to "base metal" terminations because of the difficulties in continuation of supply & stability of price. (Something about being mined in Chechnia or the Congo?) W

Hi Ing, My suggestion is to take a good look at your profile(s). The Wave solder machine that I use is an Electrovert EPK I. I use Aim ultra pure 63/37 solder with an older kester flux, 920CFX. I recently switched from kester ultrapure to the aim ba

I think the 1st option would be the best. I have found that a touch up person WILL TOUCH UP SOMETHING, regardless of the electrical needs of the board. This leads to a lot of unnecessary rework of joints. I would hope QC is tracking the defects and t
