Hi Sami, A little more detailed information would be good,as it perhaps makes it easier for us to point you in the right direction of the root cause of your problem. And then you should fix that, rather than tweaking your programs around. 1. What typ

FAI appears to become fashionable in the Bay area. FAI on double side sticky tape is the first one I hear about. How does the customer test the functionality of the board, when the board is not soldered?. Components are not wasted for FAI. Wrong part

I agree but, are there really heavy metals in this water? Our process is as follows. Print Paste Reflow Board (no components, water soluble paste only) Wash Board Same reflow profile for almost every order so no solder balling issues etc. Carbon an

SSD can be used on both sides of the pcb. Although , it is not very logical to use it on the bottom side of a pcb that has numrerous Through-hole components, that are to be wave soldered. There are many advantages to SSD. The amount of solder is much

You can't really use a pasted board to troubleshoot the program as any components not on target simply slide off with machine vibration and movement as they won't be held by the solder paste. Whereas on double sided sticky tape they remain in place

Are there indentations in the paste ? If there is, you have a couple things to look at off the top of my head:1) make sure your spool valves are shutting completely off. 2) make sure there is nothing sticky on your nozzles.3) Adjust the blow off/ "ki

This happens with either old tape, the cover tape doesn't stay sealed on the left side, or is the seal is too far to the right, the knife lifts the cover tape. There isn't much you can do in this case. Your choices are: switch the component into an A

Apparently the adhesive tape peels off from the joint, which could have some reasons. 1. There should be an overlap of the cover tape, as Cal mentioned. The new cover tape laying over the old by approx. 2mm. I also peel the cover tape a bit off, whi
