Hello George, SPC can be time consuming but if you don't track or make recordings consistently then how do you measure your process performance and overall line quality?I'm sure your customer is asking because they want you to demonstrate that your p

Chrissie, I'm glad you (and your people) made it through the painful process of reworking all those BGA's. Hope all your boards sucessfully pass test. Now on to the larger issue. In my experience, the solder paste screen printing process is (along

tommyg_fla. Sorry about being late getting back you. Surface-active species, such as Fe2+, Mn2+, NH4+, and H+, can be adsorbed onto solid phases [and transported by things as weird as bioturbation or advection not that they have anything to do with

I have come across a rash of failed assemblies that have 0805 capacitors and resistors, bottom side glued, wave soldered and washed. Trouble shooter reported touching up the solder joints on a few areas and the boards would pass test. I had a look a

Stability of process is what your measuring so lets not assume a stable process(if your process was perfect you would have no defects). With no test a medium complexity board will be around 68.7% (according to Consulogic). I dont have many other sour

Robert, what you have provided is not a "profile". It is a "recipe" or "job". I have 4 BTU VIP98's. I have hundreds of recipes...Your temps look similar to mine....but what does that have to do with the "thermal profile" as experienced by the asse
