Those are nozzle attaching and removing errors, meaning the machine is having a hard time picking up and leaving nozzles. In the head there should be a rubber o-ring, it often needs to be either cleaned and oiled (Juki has a specific oil, make sure

Hey everyone, Our company just picked up a Quad IV C/115 pick-&-place system from one of our offices that closed, but we do not have the documentation for it. It looks to be a very old system so I can't find it anywhere online and we just don't know

We recently had a question come up regarding the amount of solder on a flat underside termination ( we referenced Flat Lug Lead in IPC 610). Judging by the photo you can see on the Left is a target solder joint, but on the right is one which had rewo

I am guessing a lead free process. From the pictures, I don't neccessarily see any issues, perhaps the leads have wicked up a little too much solder, making the joint look a little starved. But I think I see nice toe and side fillets. In the worst c

So why is the number of wraps = (Outside diameter - inside diameter) / twice the the thickness of the tape surely if the tape thickness was 5mm and you had 20 wraps it would take up 100mm not 200mm. I made a posting here some time ago, over a year

Preheating is critical in Vapor Phase Soldering. One trick that is done is to use the "soft vapor" area just above the soldering vapor, some machines can pause just before going into the soldering vapor. Using that pause above the vapor to continue

Vapor phase soldering systems by Asscon are characterized by special designed heating modules. The thermal mass of the heating modules is designed so that a completely delay-less and direct regulation of the heat/flow/energy transfer to the soldering

Sorry to build up your hopes. The latest thing to hit the air ways at work, I was accessed of fiddling with the oven settings, because there were reports of "cracked joints" there was no mention of where the cracks were, cracked at the pcb or cracke

A Quad QSV-1 can do up to 18x24in. You can get these on the used market or buy a completely refurbished (like new) machine from Precision Placement Machines (PPM). I do not represent this company or am in any way affiliated with them, although they d

I think right now there is a comfortable buffer built into our process. If our pnp were 50% faster I believe that buffer would be cut out of the equation, so while I think it would be fine on most of our builds, I believe there would be builds that
