I am evaluating several pieces of Siemens equipment and would like to get some input from industry users. I am seeing that Siemens is able to meet cycle time estimates and thus throughput. I am concerned about the robustness?? Any input is welcome. T

Hi I am a collage student and I was wondering if anyone could explain to me how you would estimate the trough-put, product and cycle time for a double-sided mixed technology pcb assembly. I would be grateful for any information Thanks Martin.

Can anyone give me any information on the longivity of titanium insert wave pallets. What I am looking for is the integrity of thin walls over several hundred cycles and the interface between the insert and the durostone material.

I have done that also, It does work well. One issue we had was that the mask didn't come right off during the first wash cycle since it was put on much heavier than the mfgr suggested (.01"). We had to soak them in some water first to soften it up

We have a Viscom SPI S3054QS. Yup, the machine offers a quite good speed. My board dimension is 150 by 250mm. The cycle time is only about 24 sec. The analyze time is only about 10sec. You can make your loading faster, if that's what you needed. I ha

Hi, I have a general question about the relationship of PCB thickness and BLR testing result. For example, I have QFN6x6 parts mounted on board in 1.2mm, 1.6mm, and 2.4mm thickness. All boards have 6 layers of Cu. Studies show thicker board gives les

Regardless of the design technology of the board, we use shop floor management software that: * Calculates the period that it takes to assemble a job. Obviously, we enter product-manufacturing information [ie, BOM, material receipt dates, process fl

Thanks for the reply. When you hit start on the printer, you can see it send the "start cycle (SMEMA)" signal, and it immediately goes to "awaiting board from upstream." This tells me that the printer knows a signal has definitely been sent and rece

unique mnf/mnf part number. - Be meticulous on maintaining your WO Boms. Train your employees to not circumnavigate keeping the WOBOM accurate to what they kitted/placed on the board. If you keep the one to one part number relationship above this is

GEOMETRIC DIMENSIONING AND TOLERANCING (GDT) Using and applying GDT to printed circuitry and assemblies is very much like applying it to any other design for manufacturing (DFM) or design for assembly (DFA) requirement using concurrent engineering (C
