I was wondering if anyone has ever considered measuring the belt speed of their reflow ovens using some type of hand-held, preferably non-contact device? If so, could you recommend a manufacturer of such a device? We are considering measuring our act

What are the recommended stencil apertures for a TSOP40. Lead pitch 0.48mm & lead width 0.21mm. And direction of squeegee print over the aperture? Recommended Stencil thickness? Recommended aperture reductions? Recommended pcb pad sizes? Recommended

When printing below .5mm pitch, the recommended stencil thickness is 5Thou, laser cut. Do not use any reduction and ensure wherever possible the pad to space ration is 1:1, the length of the pad is not as important as the gap between adjacent pads. T

This may make it easy, Do you really need soak? Or can you just ramp to reflow. Most pastes that I am aware of perform just as well using the linear ramp as opposed to the ramp/soak /spike. Now, out of curiosity how are you attaching the thermocou

Water soluble pastes generally work best with a ramp-to-spike reflow profile. Check your paste manufacturer's recommended profile. There are many factors that impact your profile; board thickness, component density, buried thermal masses, board si

I started a job in SMT a little less than a year ago. I was told I would have mentorship in the form of a manager and senior engineer but both left about 3 months into my time at this position and I became the sole engineer in SMT as the senior was n
