50%) only over the appertures where there was poor support. Most prints took 2 knead strokes to print OK, but this caused fine pitch leaded devices to almost short. stencil had to be be wiped after kneading. 2 similar devices with exactly the same

Rob, Don't know if you bought an "H" tower with your UP or not. You did you can have a dedicated support plate made from Aluminum that has pockets machined out to match components on the bottom of the board. (Most of the workholder guys can set you

Please check the solder paste height near PCB edges, Please check board clamping during solder paste printing. Please check tooling support boards must be fixed during the printing process. try to set wiper cleaning frequency and fine tune for best

A good fixture is the key here. The first side should be easier than te second(if double sided). In both cases I will try to level the top of the board with the top of the fixture. Try to lock with pins comming from the fixture to the PCB holes. This

I have worked with both Gridlock and conventional pin support mostly on DEK machines. Gridlock allows to reduce greatly changeover time in hi mix/low volume environment when switching sides on double sided boards. It also eliminates guesswork when ma

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

Yes, it is important to ensure blade pressure over stencil is uniformly distributed across the entire length of blade. Such is possible only if the stencil is firmly supported from below, which during printing is done by the presence of the PCB itsel

There are concretions that form inside the chamber when using a water soluble paste. They start forming and affecting print as early as 2 days. This is apparent no matter what type of print head you may be using. There has been over 30 water soluble

I was wondering if there is anyone out there who is still using the HTI AutoPrint Screen Printers who might be willing to share technical support information. We are having trouble with the machine "finding the stencil" and were wondering if anyone
