Immersion tin is very sensitive for handling, scratches, storage condition and time, thermal influence and washing. You will get problems in second reflow if you have double sided PCB with immersion tin surface finish.

Hi Syed, I'm a PCB engineer from China. First:Immersion gold surface finish is the best for PCBs. Second:HASL(Lead-Free HASL) Then:HAL(with lead) The cheapest surface finish is OSP(After 15 days will be oxidized)

Have to second Phil's assessment of Juki. Been running for over 10 years; rarely break; when they do service is quick. Maintenance costs are consistently 15% of our sister companies running Fuji.

I thought it might be the oven too, except it seems the splatter is too small for drips from the oven, secondly, when I ran a couple of bare boards among the populated boards we saw no splatter or flux contamination. So it seems it comes from the bo

You may want to search the UIC knowledge base for troubleshooting. If you do not have access to UIC's website (second hand machine) you can call and register your machine for $500.

That is why we don't care if it is Top or Bottom. We call them first (process) side and second (process) side. Often you will have tall and heavy parts on both sides, so you will have to glue them.

Hello Is it possible to make really big placement delay on this maschine? 3-4 seconds? Thank you.

Thank you for your answer. But maximum value for modcode 7 is 255. 255x3.3 msec is 0.8 sec. And I need 2-3 seconds...

These two components are tallest among other components.Is there any method to check pad size required according to component leads?

We check the TDK data sheet reflow profile condition. We check the PCB surface temperature the max temperature is 237.Anyhow We will confirm it by check temperature on TDK point
