We are experiencing fracture problems with 0805 X7R capacitors. The capacitors seem to fail in tension; during hot-air rework they come apart in two pieces with the fracture near the metallization end. Only X7R SMT components are affected, C0G and Y

Hi, We are an OEM, so we deal with all stages of the pipeline from parts purchasing, to assembly to sales through our channel, and the biggest thing we have been worrying about is our inventory and bom conversions, as I don't want to be stuck with l

Hi All, The change over to lead-free is as easy or as difficult as you want to make it The big problem I see with this lead-free transition is that there is no benchmark of acceptability and no defect data (yet) related to visual appearance of a sol

Hi, Thank you for your answers. But I want to explain some points on which I would appreciate any comment: * Having calibrated the process, we intend to carry out the ROSE test just on SAMPLES of the finished boards. Lets say one every hour. I exp

Good morning, Once again a met annoying solder beading issue while producing board with PLL (leadless, contacts from the bottom side of the package). Board has very high placement density and beads appear near PLL package only. This package is finep

We have a Siemens S15 and an F3, which we have only had now for about 4 months. We have an old line of HS180s and an SP120 and have found that the S15 and F3 do not have the option to skip a part if one runs out during placement. We from time to time

The NexLev connector is built in a stripline construction, providing a continuous ground plane for each signal contact. The connectors come as tenrow connectors with 100, 200, or 300 positions at possible stacking heights from 10 mm to 30 mm. Technic

Howdy Amol, As far as I can see, there aren't too many pitfalls with SN100C. Just make sure to keep all of your alloys seperated. The issues that I am working out right now is the profiles with our wave pallets and some of our larger components. We

We are a small company, reletivly new to doing our own SMT (1 year) and we are having an issue, I think. We manufacture many board with no problems, but we have one that constently defeats us. This particular PCB has ENIG finish, and we have had th
