Just askin but why would someone even want to subject an assembly to even 6 reflow cycles? As far as how many cycles that an assembly can be subjected to, wouldn't that be determined my your components?

Is there a limit to how many times a pcb with components can be run through a reflow oven before the components start to degrade? Example: We load the SMT components on the bottom side of the pcb and run it through the reflow oven. Next we load the

Hi. smtguys Would you let me know the name of company appling the pihr in smt process. As you know PIHR stands for pin in hole reflow.( pin in paste) I just want to know what company apply the PIHR in smt process. I expect the contents of the c

I Kyung: I'm not sure if we are working with PIHR but we insert some pines in a PCB with a pin inserter machine, after that we run this pcb in a screen printer and put over its solder paste, and then run in a chip shooter and then IC placer and f

It sounds as if you have your AOI set up off-line, and you're "AOIing" a sampling of the PCBs produced. If that’s the case, then the responsibility of who drives the inspection really depends on how you configure it. If it's based on the number of P

Greetings all you knowledgable SMT persons! 1. Typically, for multi-layer (6-8 layers), FR4, SMT boards stored in an air conditioned environment at about 50+/- 10% RH, how many months (or years) would you allow to pass before you would recommend bak

How many times have you found that your oven was performing differently? this will give you the answer on frequency. We have a dedicated board and profile that we use to verify the oven operation. We perform this every 3 mos. and I believe that th

Yes, providing the surface of the via is solderable. * If so, how much paste? => Vias come in various sizes. Boards vary in thickness. So, the amount of paste to fill a via varies. Roughly, you�ll need twice as much paste as the volume of the via

Hi Mates, Need everyone's help on a component datasheet search. Have a Maxim P/N: 3286C, 3296C, Land Grid Array (LGA) type of component. Need to find info on thermal capability of this LGA package, specific question : how many reflow Oven cycles c

Are you sure you are using the correct solder paste question, once again. How many cycles times allow to proceed in reflow for these type of packages. => Dunno. What does the supplier say?
