Hi, I would agree with that, and the second hand prices for a TP-9 is very low, and they use the same feeders as the MY series, so if volume ever increases there is an upgrade path. TP should be able to handle any component, and because they can p

We have two APS Gold ovens and are acheiving an accpetable Lead Free profile. We still have to further qualify board widths/sizes to determine what are limits are and still be within the profile we need. For the most part you need more zones/longer t

Hi. In the past years I had made dozens of PCBs but now I am trying to get a professional finishing on them. The main problem is oxidation of the copper traces. Basically I use the silkscreen method to make the pattern in both layers and then etch. L

Thanks for the response..... The solder is actually printed okay prior to SMT.... And after placing, found missing solders at middle terminals of 0408 resistor arrays.... Package library is checked, component spec looks fine... I am suspecting the

Hi, I looked at the pictures and it looks as if it should be a straight forward solution..but obviously not. I would focus on the stencil/print more than placement machine. The placement machine simply places the part on the board!#(just one thing

We have had this problem with one of our machine although it is not a Mydata. We had to reduce the blow off time for these. Our problem was also these same Rnet packages. the part is proabably picked a little off center, then the blow off hits the

How does the mount plane change if the surface of the board is located in the same place every time ? For example: If you put 2 boards side by side on the Y wagon : one board measures .020" and the other .200" the surfaces of the boards are going

Hi Peter, I'm not sure where you're located, but I work for Celestica in our Component Failure Analysis and Reliability Testing Lab in Toronto Ontario Canada. We are an idenpendent lab with full FA component, assembly and PWB capabilities and would

Rob We agree with Jason's point about swab lead indicators. You need to be careful interpreting the results. Lead must be in sufficient measurable quantities as found in Sn 63/37 or Sn 60/40 solders. Handheld units are: * Oxford (bought the X-Met

I have a single sided PCB that contains 4 RF connectors that will require conformal coating. Sounds easy, well the RF connector is .080 in diameter and stands a whole .050 in height. The sub-straight that the barrel sits on is about .020 thick. I don
