If you use regular solder paste you will not need to process at the higher temp. Using Flux only will require you to reflow the lead free balls. When we process ceramic BGAs with the high temp/lead free balls we always use 63/37 paste and it works

Does anybody out there know what type cable is used for the controller cable on an LSM large model circa 1996? Is it a standard 25 pin D-Sub? This is the cable that goes from the XY Axis line box to the controller. I have contacted Cyberoptics and t

Dedicated tooling uses what MPM calls an "H" tower. You mount the board support plate (dedicated tooling) on top of the H tower. If boards are only single-sided SMT, meaning only components on one side, the board support plate is flat with vacuum hol

I would recommend trying a Board-lok Tooling support fixture. In my opinion, no other tooling support system or fixture compares to the type of support board-lok provides. They can manufacture the board-lok with many options such as vacuum, tooling p

Can anyone tell me if the Panasonic K-style green emboss 08x04 feeders can be used interchangably with the white paper ones? If so what is the importance of the push pin and are there settings in the machine that need to be changed? Also is this (whi

We use paper tape in green emboss feeder without problems. But you can't use emboss tape in white paper feeder because the bottom of the tape needs a channel so the tape is supported on two side. Also, we remove all push pins. they are useless. We ne

Hi,Please 1.X-ray your board where you found pinholes.perhaps you'll found much voids in your joints,but not only the pinhole.this must be caused by the poor solderability of PCB mostly...or components. 2.Cross-section the pin hole or void in the joi
