| I have a board that has surface mount on both sides . On this board is a 22pin connector which is the only thru-hole part.This part is located on the component side. I would like to reflow this part. Can this be done? If so, how can this be done?

Hi nards I'm not quite sure what your question is. If you mean is paste volume more important than the reflow profile the answer is no. Belt speed is just a part of creating a reflow profile and all aspects I.E. pasting, placing and reflow are jus

I have a less than perfectly designed pcb requiring double sided lead free reflow. Several components from either side will detatch using the standard process. If I was using Sn63Pb37 I would just dispense some adhesive after paste and cure at the r

Based on work I have been doing recently the most common reasons for component loss is board flexture and vibration on the reflow process. If parts do not reflow then weight is not an issue. There is a video on double sided reflow and PIHR from the S

Hello all, I am having soldering issues with an Everlight component it is a TM4201/TR2 (Right angle IRDA with a 1mm pitch). The problem I have is that after reflow the solder joints look perfect, but during test we are losing 7 micro amps as soon as

Greg: Heller 988s are good, solid, basic reflow machines that will turn paste liquid for 85-90% of all applications. I'm not sure what you mean by "is it comperable to the larger heller with a slower rate?" But, yes it will need to be run slower t

Because BGA's are so hard to rework, you'll want the maximum process window for your reflow equipment, and this includes an inert atmosphere. But as long as solderability and temperature profile are well controlled you can have perfect results with a

Having an issue with our paste inspector (human type). Were printing paste on .5mm pitch pads (MLF package). My question is - What is the acceptable print deviation (percentage) off the pad before you see problems after reflow? 0%? 1%? 10%? 25%?
