I need to setup an oven to run with a nitrogen atmosphere for boards with BGA's, but our ovens do not have the optional atmosphere monitor and controller. Is there a good way to sample and control the atmosphere without the optional built-in atmospe

Just bought a used VIP 98 and I have an alarm. Computer don't communicate with the embedded controler of the oven. I've check the cabling, OK, and there's power on the controler. The PC is booting normally. The controler is plug in the serial port 2

Try to check encoder if properly locked, also check encoder connector if properley inserted, if all good, it's possible that the conveyor controller or encoder problem... to check controller related just try to set in zero value, then if conveyor are

I have the following problem with a GSM. When powered up I get the error "Error Initializing Hard Disk Controller 0" do you think this is the controller if so what is the part number for a controller.. any input would be great thank you

I just started my new job and I noticed that the humidity on production floor (electronics) is not being controlled. I have some basic understanding of why we need to control temp & humidity. Do you know if there is any benchmarking/studies done on t

What are the normal control limits in the industry, for a well controlled process, using a 6 mils stencil? Should they be different according to the surface finish (higher UCL for ENIG, Im SN, etc, lower UCL for HASL)? Thanks, Ioan

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
