I had a benchtop Yestech demo until for a couple weeks. It was a very good machine. I particularly liked the RGB light system which gave a good visual representation of solder fillets. There was software that allowed you to evaluate based on the p

I am having a horrible time with the square radial lead capacitors (thru hole components) and the part coating flowing into the solder joint. These are Class 3 products. When we run them through the wave solder machine, the solder travels up the le

We are having a little trouble with what appears to be a crystalization between our fine pitch parts. The problem appears after a a thourough wash of the pcb when dry. It looks like lead wiskers/haze between the joints.We are using water soluable lea

Hi SMT World, I am facing a technical challenge related to an SOIC 14lds with thermal pad on it's belly that needs to be soldered onto PCB, together with leads. It is a 50 per board, expected 80% solder load on every one. We have some units without

I believe there is a lot pertinent information in the thread that Dave forwarded... But (IMHO)I think you can look at two things first. First, is your wave solder process friendly to this large PCB, is there enough pre-heat in the board before it h

Hi, We had it for a while, but had to take it out and replace it with normal convection. I mean the soldering quality is absolutely amazing, and the joints looked perfect, however it was a horror for tomb-stoning. We tried all types of stencil apert

I have used Unicam software to create visual workaid documentation along with a setup sheet showing BOM in relation to feeder setups, etc. This was used in 1st piece verification, but also in the early days I had to do a 2 person validation. One and

Error 215 is due to corrupt memory. I suggest that you start by replacing the Lithium battery on the Mother Board. Next, remove the cable from the Floppy unit and turn on the machine with it disconnected. Goto the SYSTEM menu and find the menu "DATA

We have a customer whom we have built boards for. They want a "cleaner no clean look". The process uses a no clean Kester 256 SN63 solder paste. After reflow the "residue" noted by the client is too much. We have tried a few things. We are a small
