We currently use the VectorGuard stencils and love them. They are so easy to set and remove from the frame and weigh almost nothing. We get very good prints, we do 0402 and 16mil. We previously tried the Tetra system and were not happy due to the

Were dealing with firmware issues for the stepper motor, as well as communications problems with the software. Vitronics is looking into it... again, but even they seemed to be stumped. You may want to ask your rep about it. Our machine is brand new,

It is also possible to etch the barcodes directly on the PCB by using a laser. The solder resist mask is easily burned by laser and if there is copper underneath the contrast is quite good. The contrast is satisfactory even if there is no metal under

Its a bit of an old beast, it was replaced by SE 200 and is now discontinued (since 2004 I believe). Its a decent unit, but hard to achieve good repeatability on smaller deposits. Its also not reliable on small solderpaste below 20mil fine-pitch. Fai

Hi, I'm having issues with boards sticking/jamming along the line, as well as what seems to be excessive wear along the guide rails. The boards are an Alumina Ceramic material and the rails differ by machine, but include anodized aluminum, steel, de

We are curently using a SMTech AVP 300, which is an in-line semi-automatic printer. Within the next 6-12 months we will be looking to upgrade to a fully automatic printer. I have already had a little look to see what is out there, and I am shocked a

I'm building a circuit board by hand and can't identify pin 1 on a smt IC. I always determine this by the beveled edge, which this part has, but it also has an arrow on the opposite end, so now I'm unsure which one I should go by...help! Ok, got my

The actual solder joint occurs BETWEEN the part and the pad. Adding more solder on top will add strength slightly, just by being in the way when you pull on it sideways. A weak joint with a weeks worth of solder on it will still be weak. Solder is

I would...and then use the data of the known issues as part of the secondary analysis. The defect is a defect, one way or the other. You can use the secondary analysis of your PPM numbers to continue to drill down in the process. If your overall P
