I have a mixed technology PCB that has SMT all on bottom, TH parts on both sides (Yes, I realize that's bad. Can't be avoided.) We have designed a 10-up panel, 2 x 5 array. There are 50 leads per bd, 500 per panel. How much time is reasonable to a

If you allow 3 seconds for insertion of each connector and 2-3 seconds for each solder joint, then add a 10-12% contingency allowance you shouldn't be far out. Maybe get an averagely rated operator to build one on the clock. Regards, Chris

Sure those products and other competitors listed in the fine SMTnet Archives provide a uniform solder deposit, how do you suggest that Russ provide the proper amount of flux and heat to properly form his solder connection?

There is not enough time in the day to reliably hand solder these connections. Go buy yourself a solder fountain and spare yourself and your company the misery. Check the fine SMTnet Archives for sources of supply. Everything has a price. A solde

Dave, In response to your question on flux and heat application; the flux is already incorporated into the solder deposit and the connector usually solders in a standard convection oven profile. If you need more details you can contact me offline

This should be fixed by someone who has access to Windows on these machines - probably ASM engineer. You are right to be worried about traceability. Also changing this time might lead to much more issues underneath, so don't just change it before ask

Traditional methods of hand assembly are as you described. For a company that is concentrating on the 1-5 or 5-50 quantities you've described, you need to look for ways to accomplish your task with speed, repeatablilty, quality and at a fair price. T

I have experienced this directly in SMT and wave solder. Fillet lift (can) be a direct indicator to lead enrichment (but its not the exclusive symptom). Lead enrichment in smt joints reduces the interfacial strength shortening the time to creep f

NO-LEAD COMPONENTS WITH LEAD SOLDER ISSUE: We agree with Russ. We've dicussed this several times on SMTnet. For instance, look here http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=25394 LEAD COMPONENTS WITH NO-LEAD SOLDER ISSUE: We disa
