A couple of points: * Just a nit, 'screens' fell in disuse 10-15 years ago. Old habits die slowly don't they? * Yes, DEK and MPM each hold about 50% of the solder paste printer market and about 4 or 5 others hold the rest. SOLDER PASTE PRINTER EQUI

Phil, I used to print solder paste on 2" X 2" and 3" X 3" 96% Alumina substrates all the time. I used standard solder printers and stencils. Screens are difficult to use and don't print well. You can use a stencil on a DeHart, CW Price, or AMI Pr

Screening adhesive can be messy but is alot quicker than using a glue machine as long as you setupyour stencil machine either manual or machine, we also use steel stencils with a stainless squeegee but you can use a rubber squeegee not sure about pre

We recently bought a used MPM UP1500 to upgrade from a manual DeHaart printer we'd been using for years. On the DeHaart, all of our stencils were 15" square. We purchased at auction a stencil adapter for an MPM printer (ie: 29" wide), however it's

Hi, my guys did such solder paste deposits on PCB bareboards before, (before my physical join with my current company), approximately 2-3 years ago, for a small Lot run. What the PCB supplier did was to apply "block" shaped Sn/Pb paste alloy onto t

Hi Dave and Justin, Thanks for the advice. Dave you mentioned you "smush" your bga's. What type of machine are you placing then with it? Is the additional pressure to smush them machine or manually applied? Also, the 0.004" variance we are being

Hi, Please help on this problem with an MPM AP25 screen printer. Everytime we print the error Squeegee Pressure Not Set is prompted. Although we can still print by clicking on Next, it beats the purpose of having an automatic printing machine. Can s

This solution is not as complicated as you might have thought. T-conveyor connected machines are widely used for applications requiring high material deposition throughput. This solution is made of: 1. Two independent screen printers 2. Two line loa

We are a small OEM that runs a high mix/low volume environment. Typical runs are a couple or five hundred boards, one or two products per day. Currently, we are using a Quad DeHart SLC-20 semi-automatic stencil printer. (alignment is manual, printing
