We have a My500 at out plant. We are high volume and low to medium volume. It is a great machine and is a great solution to some problems that a conventional screen printer cant get around. For example, we have some producets that are not flat on

"Any risks associated with double pass stencil printing?" Mostly just too much paste, plus the associated bridging, and your stencil gets dirty quickly. Any gap between the stencil and the board gets filled with paste on the first pass, then migrate

Sounds like you need a support pallet to accommodate the narrow side clearance. Several pallet houses made pallets that work in screen printing that have flush board edge clamps that hold the board in the pallet yet allow the stencil to come all the

Thinking about this auto-mode on Grid-Lok..... Ok, the board is warped, lets say positively, the pins conform to the warped board... what about the effect on top side and squeegee pressure? It will be much higher and could damage stencils, right? Pos

Viewing a blade on its own merits may give you subjective results. Are you asking about metal or rubber squeegees? You really need to examine the print quality before you decide if a blade is worth using. If you are getting the right paste deposit vo

Is your stencil worn out? If your once flat stencil is now wavey, you will be depositing more paste. Ideally, you'll have historic SPI data to compare known good volumes from past prints to the current. Another possibility is moisture. Bake your boa

The SMART Group is starting a new project on PPM Monitoring which will be providing average PPM yield data per month free to the industry. I would like to get feedback or exchange criteria for paste printing as non exists with in IPC or similar organ

I would consider the fab placement in the printer to be of more concern than the pro's and con's of a single foil for top and bottom print. Do to the larger size of the fab you will have to align the top and bottom layers sequentially on the foil. O
