Hello everyone, I am curious what do you think about stencil type and apperture design for better release on small appertures. I have a PCB with bunch of BGAs with small appertures. We tried with Nikel stencil using DEK's special non stick material

Things that come mind are: * Not sure why you want to do this, since probing solder gives a longer probe life than probing copper. * I've never tried it, but I see no reason why you couldn't probe Kapt0n or blue painters tape. * Fabs [or you] can pri

Hello, We need information regarding the specifics of soldering Nickel Silver in a reflow process. Is there a specific process / flux / cleaning / Temperature curve / or whatever required in order to properly process parts from this material? Nicke

Use a standard that everyone will recognize. If you say, "The solderability test was performed in accordance with ANSI/J-STD-002 'Solderabiility Tests for Component Leads, Terminations, Lugs, Terminals and Wires'” [ipc.org/TOC/J-STD-002C.pdf ], every

Hello, we have a DEK 248 just acted up with the squeegee orror. unit powered up initiated and when throght setup a job fine but when we started printing, the back squeegee came down, touched the stencil, stay for about 5 second then came back up with

I had this problem once a loooooooong time ago with a 248 that was at my previous place of employment. If I remember correctly, my issue was caused by a set screw on the drive gear that had worked itself loose. My issue was stright forward and quickl

Most likely it is a faulty cable in the e-chain . You can test it in diagnostic: lower the back squeege and manually move back and forth for its entire travel the print carriage while monitoring the sensor output of the squeege. You will see at some

I am trying to use Mydata TM8C feeders that work fine on a TP93 running 1.6.18 TPsys but are not recognized by a TP94 machine running 1.4.7 TPsys. I get a green flashing light instead of a solid green. I can initialize the hardware but can not proc

Quite sure it is one of the follow things. Squeegees are not tall enough (using after market blades); Are you using a stencil adapter? bottom surface of the stencil must be even with the top of the stencil shelves; printhead assy. is modified, faile

Does anyone know the mechanical differences between a TPsys 1.6 version feeder and a 1.4. I only need to have one feeder for the 1.4 machine and would modify a 1.6 feeder if that is an option. Otherwise, does antone have a 1.4 version feeder they w
