We had a SMT specialist come in and go over everything we were doing wrong! We were dipping the boards rather than spraying them, had the pre-heaters set way to low, the conveyor was going too fast, and the actual wave was in the machine the wrong wa

The boards are expensive because they are your product... covered in circuitry. A 2% scrap rate costs twice as much as a 1% scrap rate. Say the parts on your consumer electronics board cost $5. A machine that makes 99% good boards and 1% bad boards

I have a few questions: Why are you unable to panelize an aluminum board? We run aluminum boards all the time utilizing both V-Score and Routed designs. Panelization aside, what are the issues that you run into at printing? Are you trying to print

Many Manufacturers make Large board capable machines. A quick way to find them is to look for LED machines, the lengths should range from 32" to 52", although some simply manipulate the staging (clamping) area to achieve length. The trick is finding

On a previous black pad experience we soldered a wire to a fiducial and did a pull test to failure. On the black pad board the wire and solder pulled of clean leaving the fiducial on the board. On good boards the copper came off with the wire. If you

Suspect comms link error from Y3 to Y1 crate. COM 2 off of CPU, depending on board. If CPU board has RS485 port it is direct to back panel of PC; if older board it only has RS232 and thus requires 232/485 converter board (internal to PC). then direct

Our MPM Up2000 HIE is having a communication problem with any upstream machine we place in front of it...i.e. conveyor, board loader, etc. It all started when we removed a conveyor from inbetween it and a board loader, and hooked those machines up di

I have many PCBs that use an AVR in SMD packaging, and since I frequently change the firmware in prototype boards, I'm trying to come with the best solution to program the AVR quickly and easily. The first approach was to have a standard header (2x5

A lot of our PCB's are being damaged by our water cleaner, it is a Steolting Triton, and I beleive it is due to the drying section in the machine. The air its blowing on the boards is flipping the boards around on the conveyor and smashing small deli

Yes it happens with any inline cleaner with small or light boards the pressure can cause them to flip. If they lodge in the links they can also cause damage to the conveyor. For small boards, flexibles etc you do need a mesh fixture of some sort or l
