We recently purchased an IBL VPP-M600 vapour phase reflow oven. We currently only have partial documentation and need to know the requirements for the water cooling. ie flow rate, cooling power etc. We also need the spare parts listing and service ma

I talked to someone regarding the Biral oil and they said that they have had a problem with it "jelling up" when exposed to oxegen. Has this been a problem for you as well? I ordered some Stabylyn 773ND from Vitronics. I hope this stuff works for 57.

Rather than go into detail here, try googling "classic reflow profiling". One of the guys at ECD (a thermal profiler manufacturer) wrote a pretty decent article that covers most if not all of it. You DO have a profiler, don't you, or an oven with

Hi, My oven has 5 zones each 12 inches in length , giving a total of 70 inches Heating Zone in total. I am working with a 6 layer PCB ,ENIG Finish. I am using Alpha OM338T no-clean Solder Paste. I am working to a cycle time of 4 to 4.5mins RTS p

Could be not enough peak temp. Do you have a profiler? I'd measure at the BGA joints- drill under board to get access to BGA solder joints and embed a couple of thermocouples with hi-temp solder, then run your profile to see max. temps. and that prof

I can't answer for wave, but we tried some Sn100 paste for reflow, and couldn't get it to work worth a darn. I then got some SAC305, and was relieved to see it work almost as well as SnPb at its best! Much better wetting and flowing to the various

Could be any one of the 3 you mentioned, need some details here, do you really think we can answer this question as it is? Now for your issue, what is the make up of the lead itself on the part? what is the reflow profile at this part? what is

Hi, Thanks. Waitng for your reponse. BTW, if I were to perform a test as below will this give me some result to indicate if the component is defective. 1) Print solder paste on plain PCB without copper track. 2) Mount the QFP & reflow 3) If the sol

You mention moisture in the part as a cause of cracking during reflow. What does this type of crack look like? How was it determined that moisture was the culprit? The resonator is near the middle of the PCB, but is about 5mm from a large hole (abo

currently i'm open my stencil aperture is 80% from the land pattern. is this will cause insufficient solder at the terminal component or not? the stencil thichness is 6mil and the board run using SMT pallet which i consider there will be no option f
