I'm curious to people's findings. What is the life span / expectancy of your SMT machine? Recently, I heard, through the grapevine, that Fuji listed 5 years as a lifespan for their machines. After that, they would either need to be retired.

We have Siemens machines 0f 1992 Vintage to run daily and we do not have any problems with them.

Lifespan and Useful life are two completely separate items. I agree some mfrs machines are mre robust than others, but there is typically a trade off. As Sr Tech intimated, PM is the key to keeping all machines humming.

In order to burn (old fashioned) E-PROM, I can't always verify the vendor of an IC on the print. The logo is very likely the initial letter of the manufacturer, but sometimes it requires imagination to read the letter. Could somebody guide me to a li

We seem to be having a problem with our stencils delaminating from the emulsion quite frequently. Does anyone else out there that buys stencils from Microscreen have this problem ?

Dude - one thing you may want to look at is the detergent your adding to your stencil wash. If it's geared for epoxy removal, it will also remove "that" epoxy as well. The rule of thumb is, under one year, the manufacturer fixes the stencil, over one

Se�or Tech We use stencils from other suppliers. So, we have no specific problems from Microscreen. Generalizing, most stencil manufacturers recommend that their product not be exposed to temperatures in excess of 110*F (43*C). Our old buddy B S

Hi, Yes you can use a PWM (Pulse Width Modulator). This is much more efficient than a large resistor & gives you good control. Here is a sample for 12V motor control: http://www.homepower.com/files/pwmhp75.pdf

Is the a good, cheap automated way of labeling the trays that PCB's go on? We currently use masking tape with assembly and work order numbers but half the time we can't read the operators handwriting. We have looked into some label printers, but not
