I agree with previous postings regarding print speed: Solder paste type/versus fine pitch. Question: Is this a double sided pcb with fairly easy component packages on both sides? In such case, consider make the panel like this: Every second pcb in

Hello, I'm a student assistant in a research project that deals with the simulation of PCB assembly systems. At the moment I collect information about SMDs. My problem is how to assign the correct feeder width to various devices in a simulation. Is

| I am interested in seeing how some of you quote smt work. Currently we quote off a bom without component packages known then look in data books to find out what type of component they are. This job will be mine soon but i really believe there is a

Grant, By flex machine I simply mean a machine that can place the entire range of SMT components. I don't consider the majority of Japanese machines to be truly flex machines because they are always presented as two machine solutions. The first mac

Hi, An answer to this question is very complex. The amount of components and their type is only one parameter to determine the level of failure. Additional parameters that can influence are: 1. The density components on the card 2. Machine type and

Our company has a process standard that requires a double person check at the beginning of every run (size of run is irrelevent, whether 20 panels or 500 panels). Every changeover that occurs a first piece inspection is made before reflow. If all is

If the machine is on it's way..... Question is 1. What if the machine is on its way / remote site...and need to estimate (say 90-95%) probability ? A1. 1 x 8 hour shift 65% x 1 of software estimate or stop watch estimate run on same machine in a dr

Peter: This isn't what you asked for (I think), but it may be neater. Source of SMT links (jumpers): Most resistor suppliers make zero ohm resistors. Size � 8mm - 10mm (.312in -.4in) long: Most resistor suppliers package these resistors in comm

We have had a few large human error, wrong placement in the SMT set up over the past year(same package size placed in the wrong feeder position to where it goes unnoticed) and we are trying to look for possible process improvements to prevent this fr

You have 4 SMT techs and 1 feeder tech? How many lines do you run? And what size is you load? These questions just came up, because I'm an SMT Technician. there is only one of me at our company,Fortunately we have only one line, but it's loaded 250,
