Hello, I would like to ask you if there is some formula how to calculate PTH hole and annual ring for pin in paste technology? Thank you. Mekmat.

Yes, you need work with supplier to see if can run pin in paste for these connectors, even do some experiments. A step-up stencil would be good for these connectors, also connectors pin size and length match with PCB hole design.

Hey all! As background, I recently purchased a full SMT line for my company. We have a DEK 265, an assembleon opal xii, and a Heller 1500. Currently our jobs are leaded, and the heller is working perfectly. An upcoming job that we are potentially g

Yes, unfortunately a lot of datasheets these days do not contain the temperature resistance to determine if it can handle the PIP application. In the past I have always used a 250 C at a min of 5 sec for the material. Also, the part should have sta

Ideal situation is get a technical rep from the solder paste supplier. They know their paste better, and should be able to work out a profile based on their paste and your oven. Again, a technical rep, not the sales guy.

Oh, well if you can profile, model your profile to the profile supplied by the paste manufacturer. Anything outside of their recommended profile is all experimantal.

What paste are using? You should referance the manufactures time and temperature specification. Running lead-free in a 5 zone oven can be done with out a problem but it is not production friendly. If you are concerned with through put I would look fo

You can keep only the 5th zone as the reflow zone. And lower the first two zones to keep a good ramping rate. Meanwhile,please note the ting temperature in software or control panel is not the exact temperature in your PCB, you'd better get a KIC or

Take a look at this. Remember, these are only guidlines and can not replace any paste specs. As Real Chunks said, a profiler will be of HUGE help. We use this to determine what our top side temps are and to see if we have any problems with heat sen
