Folks, I use both UP1500 and AccuFlex. The basis for this machine was bought from SMTech several years ago as the SMTech 500. They sold off the last few SMTech machines with the MPM name on them (stupid move because they sucked), but then quickly r

First, it depends on the alloy composition of the solder. As you might know, eutectic Sn/Pb solder has the lowest melting point among available conventional solder systems. (except those based on Sn-In and Sn-Bi systems.) For example, 63Sn/37Pb - 183

How does a fiducial work? I am going to venture a guess as how it ralates to the parts you are trying to place... A PCB fiducial is a landmark. The fiducial tells the machine where the board is located in the machine. A single fid can only deter

How well should the fiducial be centered in the teach mode? Consider that you see the fiducial with probably 40 times magnification on the monitor. If you see the cross-hair a bit off center, then this is most likely just by a few hundreds of a milli

Normally when I run into having to hit the ESC key to step through this is the steps I take. 1. Power machine down and restart. 2. Home machine and watch cutter carefully. Both cutter should acuate and the height motors should run CW and CCW. 3. You

Dreamy It sounds like you are having fun in your new job. Saponifier. Alkaline chemicals, added to water, that convert rosin/resin flux residues in the water to soluble soaps. Generally, saponifiers are better if used in an aggressive spray-in-ai

My favorite kind of calibration is where the machine learns what it did incorrectly. Then fixes itself! However, there are many types of machines that rely on human feedback as to the results of what it did. nozzle calibrations involve many factors

Hey Dreamy, Dave is correct. If you attempt to clean your water soluble (OA) flux with water only, you will turn the no-clean flux white. No inspector or end-user will accept this. If a proper cleaning system is not available to you, then I would

You are correct in understanding that the vision system comes into play for subsequent boards- to align them. Yes- if you missalign the first board and set the cameras to that board, all subsequet boards will not be aligned. Mylar is a thin polyester

Ricardo makes some good points. My idea of a dream line is one that flexible to run as a high mix/low vol and low mix/high vol. I personally like Dek printers over MPM. The new printers from Mulara look interesting but they are a new company with a
