I am using PCBs fabricated by ISOLA HR370 material. The layer count is typically 8-10 layers. thickness is 2.0mm. What is the optimum time to bake prior to assembly. What is the Standard refereed to,

We have successfully implemented this dual Process You can use any printer that supports Board width 500mm. SMT Dual Process Maximum PCB Width should be (500-20 / 2 ) = 240mm Max (PCB width )Printer support = 500mm Top width + Bottom width

EIA-481 standard allows the maximum pitch on tape to be 4mm less than the tape width (12mm width and larger). So it is within the standard allowances. As for how common 20mm pitch on 24mm tape is I can not say. I am surprised a 24mm tape feeder ca

WE ARE USING MIRAE MX240. ON THIS MACHINE, THE FEEDER ADVANCE AND THE FEEDER PITCH IS CONTROLLED BY THE MACHINE/SOFTWARE AS OPPOSED TO THE FEEDER ITSELF. OUR SELECTIONS FOR 24MM FDDERS ARE 4,8,12, 16, AND 24MM.I WAS WONDERING IF THE 20MM PITCH WAS UN

Hello, about 20mm - some kind of inductance for this week. If I were you, I would check another brands of ovens too. I mean why the clearance is so small and why they want to charge you for their mistakes? I would insist to do that for free. Next

We are a small Contract Manufacturer and have received a project which has BGA's on top & bottom. 2 larger BGA's on one side (~_20x20mm) & 3 smaller BGA's (~_8x8mm) on the other. we plan on running the side with the smaller BGA's first but need som

There is a small cylindrical sensor on the air cylinder that that actuates the chuck. I can't remember if there are one or two. Its (they) are about 4mm x 20mm and I think (it) they have a signal light. Make sure it is mechanically working properl

VG foils are about 5mm thick and two in the rack takes up just under 20mm, so admittedly not a ton of space savings. That's not the only reason I like the VG system though. It takes multiple failure points (screen tension/mesh adhesion) and reduces
