Typically TH equipment has 2240 Unused steps if no pattern is loaded when running a pattern it takes up whatever amount of steps deducting from the 2240. With no patterns loaded in my axial machine I only have 246 steps. Would this be a time to relo

I've been using 29x29 framed screens for years. I have a company that has come up with a adapter that would mount in my screen printer and utilize just the foils of screens. It basically fits and is clamped into the adapter. I am struggling with floo

That is all we have ever used ("Zelflex" by LPKF). They work great. We have 300+ stencils stored in print drawers, probably 3'x3'x5' area. The stencils are also cheaper by more than 1/2 from our supplier. The only stencils we have in permanent fra

We use QTS and Vectour guard. I would prefer Vectourguard - it is very siple to set it up. However, you have to check the tension of the stencil everyday. I wouldn't trust them as 29 inch hard frame. It is always a metter of quantities. If you deal w

Has anyone come across any good visuals for the solderability requirements for component leads with toe-down configuration? IPC-A-610 does not have any visual aids for this category and our inspectors are having a difficult time assessing based sole

Hello Can someone recommend a cost effective solder printer that does not require stencils. We are currently using a Speed Print 200 machine but this requires us to spend a lot of money on stencils and wait long lead times for these to be manufactur

The only thing I have ever heard of that prints solder paste (accurately) without a stencil is a Mydata MY500. You can buy thousands of stencils for what this machine cost. You should not have long lead times on stencils. We get ours next day for no
