Hi Processman, I would say that 92% is realistic if you have low mix - high volume manufacturing. In this case, the only reason for the machines to stop is to: - change reel (on ASM machines you can splice them together, so theoretically with ASM

We have a PCB rework dilemma involving a reflow profile. This is a SAC305/Low Solids (aka no clean) process where we are currently hand soldering (5) components that were DNP. The boards have an acrylic coating and we take off the acrylic at the par

I would switch PCB shops. Unless your oven profile is out of spec, consider a different PCB supplier. We have sourced very high volumes of PCBs (4L-6L) from offshore and can recommend a list of quality shops. Shops that we can recommend are: Sunta

I have used LTS (Sn57.6%Bi0.4%Ag) solder balls for soldering on Ni/Au pads, and I have observed a wrinkle pattern on the ball surface. When you attempted soldering on CuOSP substrate pads under the same conditions, the surface appeared normal. Additi

We have the standard profile as a template made according to the solder paste specs. For some boards we measure the result at 2 points, on the board itself and on top of a sensitive SOT263 module and adjust accordingly. The solder paste is well kept,
