No, there is no operator sitting before the oven inspecting the boards. Like I said this problem is so random, sometime I do not hear from production for days. Then there are days more than once a day it happens. We are using

Have you checked the component height in the package data to ensure that it is the same? how about the PCB itself, could there be some warp or twist thay may cause the component to be dropped onto the board? any support problems? this is all I can

Part is being pre rotated already and I also changed the nozzle size from 15mm to 17.5mm this morning. There is no board warpage at all and production is watching for it while an operator puts on a barcode label.

My company is just starting to do double sided smt. What options are available for under board support for printing and placing the second side? We are using a Dek 248 printer and Samsung CP Series placement machines.

Jim Zanolli of Teka Interconnect did an "OnBoard Forum" a couple of years ago [ http://www.smtnet.com/forums/index.cfm?CFApp=2&forum_idx=44 ]. He certainly would be a good point of contact.

boards greater than this spec. can cause latent failure, Do not confuse no-clean assembly materials (nocleaning required) vs. clean chemistries that must be cleaned. You do not want ionic contaminants on your products.

usual solder cream has a viscosity above 800 000pas at 25�C for each 1�C the viscosity change about 30 000 pas at 15�C you will have nothing ( 37% of viscosity less)on your board...
