You are not correct in assuming bot side temp as related to top side. This is entirely dependant upont the board. e.g. a PCB that is .4mm thick will almost be exactly the same temp top and bottom whereas this 2.4mm will be significantly less at the

Are they worried about the top side SMDs too, or just the bottom side? If it's just the bottom, maybe you can just glue them without reflowing. That way they won't be at risk of cracked solder fillets after AI. Granted, you'll probably be glueing pa

My name is Stephanie Baldwin. I work for USI and have been following this forum. I would suggest that you give both USI and Asymtek the opportunity to coat a sample board for you. You can then compare the two technologies side by side. If possibl

we do a similar thing but make the template from paper, we just print out an image from the gerbers (to size) showing both sides in different colours, we set this down on the table (had to work out first where the correct position was) then we place

I remember way back when we had a finger taping machine. I cannot remember who, what, or where, but I would bet that they are still available. Basically just ran board thru machine and both sides or one side would be taped. It was not conveyorized

I just wanted to know if anyone stores their vacuum sealed bags on their sides instead of flat. We are trying to save room, but I dont want to create defects either. The ones we have are tightly vacuum sealed and would like to store on their sides

On one hand, nothing in 8.2.5.4 that states that you need a heel fillet. It only talks to the length of the side fillet. On the other hand, we suggest that you should use 8.2.5.6 to determine if your heel fillet is acceptable, after you have determ

I coated three other bare boards on one side this morning from two different suppliers. Two of them had exceptional adhesion and one was so-so. I ran them through the reflow oven, coated them and got the same results on the other side, so it does not

I think this is the same material we used in the past, and when we ran out could not get ahold of them. we have yet to find anything as good. were you saying you could not re-order as well and are looking for something new? check out tesa they make a
