Well Gary I just did a long search as well and I can find nothing either. Maybe I ate too much rosin in those days? Good luck Russ

Yield on 0402 SMT Printed Circuit Board Assemblies

Electronics Forum | Tue Jan 02 18:04:18 EST 2007 | russ

way too low of yield. with that technology on the board I would expect about 98% as well. So what are the defects? and more importantly, is your design, machine(s) and/or process(s) capable of this technology? Details I am sure are forthcoming R

What I would suggest trying is to only use your bottom heaters in your oven. In this way the board will receive the majority of the heat and conduct the heat to the component. Since your components are small and your board is more then twice the stan

davef is correct. The solder is indeed wicking to the hottest part of the leads. Slowing down the conveyor will alloy the board and component to come to temperature at a lower delta T.

Agree. Drop the conveyor speed.....and drop the zone temps accordingly. This should allow the board leads and components heat at a more even rate and stop the over temp. issues. I do not suggest running only the bottom heaters this can bring new issu

Good afternoon, Profile your oven. Try to increase soak zone as much as possible. This must equalize temperature across the board and leads to prevent wicking. �Spike� as slow as possible after long soak. Do you use tooling for this PWB in productio

As a sidenote, if nothing of the above works, IPC 610 states that it is accetable (class 1,2,3) for solder to touch a SOT body if it is plastic.
