| | | Hi, | | | I just cheesed my previous attempt at this. I looked through IPC 600 and couldn't find anything relating to dimensional stability of a board with regard to stretch. I found bow and twist but nothing on size. I have a PCB that is .0

I have a question regarding is there any trick/tip able to quickly identify if a component is not clean/washable? Or a list of mfg p/n which already know are not clean/wash? We have an assembly would need to change the process from No-Clean to Clean

Thanks for all the input. Going to try vapor phase. We have an Asscon Q300 demo. I'll post results when we have them. Jim

The solder that we used is kester EM918 and Multicore LS328. Our printer machine is DEK-photon, this machine has supply below 300mm/s. the datasheet solderpaste of speed range is 30 to 150mm/s. when we produce the keyboard of the moble phone, this bo

Thank you for your comments so far. I believe I threw some people off by my wording. Clarification: How feasible is it to run a board straight into the reflow oven without inspecting it first for any placement defects? Is nudging parts and performin

128MB in any system is ridiculous these days. While we have some machines at work on the production floor that only have 128 - they're only used to view BOM's, etc. Check http://www.pricewatch.com and buy yourself 1GB of RAM for no more than $100.

Hello Sir, Thanks for your reply. i just got a mail from the DIMA service group and they said the Oven setting is as follows: Max temp settings in each zone (Which is not the temperature on your product, but close to where the air flow comes out of

The 300 degrees is the temperature as measured at the sensor. The actual air temperature just above your PCB may actually be much less. If the oven is properly calibrated then the 300 should represent air temperature at the board but I have seen ma
