We are using MPM and DEK printers, what are the critical variables for measuring print process capability?

We have been doing BGA's for years now, and I would suggest updating your profile and place a thermal couple on the BGA, keep in mind the bigger the part the more heat it will need, We stencil print all of BGA's from simple bga's to complex ones, you

Hi, If your using NXT to place these BGA's then you must be doing large runs. BGA's are the most easy part to place, and don't worry about them. Just stencil paste down for them as any other component. But we use 1:1 reduction on our stencil, so we

Dave, yes, your assumption is right, We only do washing after the second reflow. The timing from the post primary reflow to wash is no longer than 2 hour. The line config is as such : DEK265 � 3x MV2F- 1x MSF � BTU - AOI � DEK265 � 3x MV2F � 1x MSF-

Yes, there is a way to print solder paste into through holes as well as for SMT devices. I suggest you contact Alden Johnson at MPM in Franklin, MA (website info at http://www.mpm.com) about what he has done here. The trick in getting the solder pa

Dear all. We SMT line based on unversal machine and we are using DEK machine for printing with the two processes ( solder paste and glue ). I have seen that we waste time in Glue process using DEK machine because the machines are very quick than the

Thank you Pavel for your interesting. Speaking on tact time ( machine speed per Board ), our Universal machines are too quick thank DEK machine, that's why I am thinking to add another machine in Glue process. FYI, we are working on Satellite receive

Dear Sami, Consider doing DOE it the printing speed is a point of concern. A few questions: 1. Which glue do you use? 2. What are the printing process parameters you have entered into your DEK? Could you list them here (front/rear printing speed, s

Hello Sami, if your placer is faster than your printer you must have very few components on the board, how many are there? What is the tact time of your mounter for this board, what is the tact time of your printer? How large is the board, can you s

Dear ERhard.Our placer are Universal Genesis machines and the screen printer is DEK Horizon 02i . for Maian board the tact time in the placer is about 14 Sec and the printer is about 22 Sec. Means there is a big waste time . for Front pannel we are u
