Other areas you can focus 1) Find out alternative chemical and solder materials for lower cost. 2) Set high power consumption machine (such as Oven and wave) to idle mode when not running to cut electrical consumption. 3) Reduce the used of N2 gas.

Great advice!........Single tier feeder set-up carts are also available through Universal instruments directly for this exact purpose. Most people who really care about this changeover time have "pit-crews" that work in the component storage areas, o

Siemens is an excellent platform. To reduce your scrap:- Carry out the specified maintenance, especially the segments and valve plungers; Calibrate revolver heads to benchmark. Remove the tables, smooth the magnetic strips, clean the mounting faces,

Hi mike The solution is simple but two fold, first your process needs to be changed a bit, you need additional feeders to pre-stage the new P/N run and prestage the extra feeders for reload as certain higher volume components exhaust. The idea is t

Good Morning Everyone, We have a customer that produces RF based assemblies. We are building several board types for them, all of which have an "RF" area of the PCB. This RF area does not have any mask to define pads. There are also several issues w

I have used a 10% area reduction with home plates on 6 mil stencils with good success. If you're using 5 mil stencils you might go with 0 or 5% reduction.

Pat In response to your questions: Q1. How did you measure the area reduction (loss of weight or reduction of diameter/thickness)? A1. We measured the starting and ending diameter. Then calculated the area [assuming symmetry]. Q2. How did you tak

Hi Guys, Need your good advice about this for a 5 thou stencil thickness: 0603 pad is 50mil x 40mil 0805 pad is 75mil x 45mil 1206 pad is 70mil x 50mil I want the above apertures to be in IPC STD Homeplate Design + an area reduction of 15%. Will t

Dave, Great to see you more involved in the lead-free. I assume the tests you have done were in lab environment, would it be possible to explain how you measured the area reduction (loss of weight or reduction of diameter/thickness) and how did you
