Bobpan ..Thanks for the 1st input Let me ask in a little more detail The controller on SMT machine will understand the X-Y positions to mount the chips/transistor based on a given centroid in gerber file---the software on machines like Fuji, Assem

Probably not on the whole job, but maybe the 1-5 boards that were used for setup control. Especially MELF's are not super process tolerant. I'd probably allow standard caps and resistors one more time, but I'd need some test data to back it up. I'd

Thanks to all for their inputs. @Hexielectronics, I am now trying to assemble the board by attaching it to a frame and removing the frame while waving it. I plan to put the boards back on the frame after the board cools down. Could you explain more

I used an off-line paste height measurement device to control my paste process. I did not inspect every board, just a random sample once an hour. I have used both manual and automatic devices. I like the automatic becuase: 1 - I have no "operat

I have worked with Macola, MAS90 now BPCS ("B-Pics"). They are ALL expensive too. To me the MAS software had the best interface and was "easier" to teach an operator who needed to pull up a BOM for a job or to see about missing/short kit items. I

Greetings. I have noticed quite a few postings lately to the effect of "hi, I want to be a SMT pro and make circuit boards, help me". Try to understand why folks on the forum are cringing at your proposal. All of the feedback I have seen regarding yo

Basically you need to do two things 1 Look at and print drawings you get. 2 Keep track of where those drawing are stored. LOOKING AT AND PRINTING DRAWINGS YOU GET. Use: * Same software that your customer used to create the drawing. [Oh, lots of cu
