John, My best guess is the "Y" encoder - or the encoder cable. The encoder is a part of the motor assy on the QSA-

Just to clarify, you are talking about the inner black box not driving down and not the pneumatic function that brings the tactile assembly closer to the stencil? Sometimes the pneumatic shafts get slightly bent and the assembly will not retract. T

Sounds like air pressure is set O.K. The next thing to check is that the platen surface that the x and y axis ride on is perfectly clean. After that, you should knock the camera off the platen and make sure that all of the small air nozzles are blo

| Hi folks, | | I am looking for inputs on a long-standing problem encountered in our shop: Bottom-side parts (passives) falling off in the Wave...where the only remnants of the part is a flattened glue dot of proper diameter and volume, and somet

Hello everybody Lately our machine has been working pretty well, but it can’t last too long. Now, during this week’s production cycle, it began to increase the component’s reject rate to alarming levels (obviously the operators reported me when the m

Scratches do not necessarily mean bad! Usually the forcer motor fails before a platen. The motors become weak or don't evenly distribute the supplied air, which causes them to tilt and drive into the platens. Mechanical misalignment of the VY forcer

Giao, These style of MPM's use stepper motors, but no feedback like an encoder or a resolver. In other words all axis positions are assumed after "Reset" of the machine. Because of this style of drive system there is the potential for the vision ga

| Hey youse guyz... | We're finally getting our first real job at the start-up I'm working at. It's actually a pretty unique little board too. Simple as all get out, but unique. You're not gonna believe what this goes into...guess? (I bet ya' you'll

I like what you're doing. 20 years ago anyone, hobbyists and tiny garage-shop companies could create electronics devices just as sophisticated and cool as big corporations. Today, SMT has largely trashed the creativity (and competition) that existe
