Hi Yannick. This is an issue that we are just recently getting into but here is some ifo that I have gathered so far. I have seen/ used 2 different rework machines. The one we have bought is a 'PACE TF2000' which was at the lower cost end of the mar

Dear proffessionals! Question is about this alloys - Sn99Cu07 and Sn100 (Sn100C,Sn100Ni+ etc.). Is it O'k to mix them? In my case to use Sn99Cu07 as addition to selective soldering machine bath with Sn100C? Main components are the same, but minor add

Sure it's conceivable that thin HASL can cause tombstoning. Harkening back to the ample discussion in the fine SMTnet Archives, tombstoning is caused by an imbalance in solder surface tension between the two pads of SMT component. The source of thi

The results from an experiment comparing 27 different combinations of pad dimensions concluded that the pad design with 15 mil pad length, 12 mil pad width, and 9 mil pad separation produced the best assembly yields. A 5 mil thick laser cut stencil

Your fluxes are required to be compatible per J-STD-001. I wouldn't even attempt mixing no-clean (rosin) and clean (assuming water soluble) fluxes on the same assembly, especially if the fluxes are from two different vendors. If your paste and liquid

So others can solder the same board and part but you can't. Dipping the legs in flux doesn't help. Then it's either your pre-heat or wave. Measure your pre-heat and compare to others or flux mfger. Do you have chip wave or something like an Omega

Is it feasible to have one type of board carriers to take boards thru 1) glue curing process for first side and 2)invert carriers with boards, and 3)reflowing second side, and 4) do manual stuffing of th components and 5) take them thru selective wav

Brian, We have the Mirtec Table Top. It is very good at detecting the component and orientation. It is however only as good as we program it to be. We have seen some limitations in respect to solder connections. I have not found it to be 100% re

For what you have right now I would recommend that you use soldering iron tips that are made for component removal. until you get BGAs I wouldn't worry a whole lot about the expensive rework equipment. I would use specialty tips and a heat gun wit
