Sorry Duckman, I am not Valerie but I am going to answer you with what we did and do. We will either pin in paste or utilize selective wave pallets. Russ

Yeah, perhaps lean more towards a ramp-to-spike profile - reducing the soak time and add a littel heat to your temp above liquid. This has worked for us with water soluable paste as we are not required to use no-clean and utilizing a 6-zone oven. G

I would like to enter the discussion by tossing some numbers in. First of all I don�t like the 3 Sigma value. 3 Sigma are 2000 defects per mio. if I remember correctly. This means, if you have 200 components on the board, then every 10 boards have on

There are three versions of the CSM84, old, older and really old. The older machines can only do fun things around the PCB if you toggle RUNMODE 1 from AUTO to be UTILITY... then you can use the utility program "PIC" to trace around the PCB or do min

Also to diagnose if it is the correct axis go to the "calisim" or the "axis position" option in utilities and get to the "current position" menu. Estop the machine and move the relevant axis by hand and see if the encoder count goes up.

It is evident that the SMT process affects the results at testing, hence I thought this was relevant to this forum. An alternative to the NEMI (National Electronics Manufacturing Initiative) PCB test cost model (see http://www.nemi.org/newsroom/PR/2

We will wave solder a board with SOIC14 and SOIC16 parts on the bottom. It has been difficult to find any specific wave solder process recommendations from manufacturers of the SOICs. The pad geometry utilizes theiving pads on both sides to reduce br

Unfortunately, smt machines are not like TH sequencers. But, that is in their favor. Multiple reels, multiple part types, many positions = very flexible. Offline setup is paramount to line utilization. Remember, you only make money when the machi

Soon we will be manufacturing board assemblies on our SMT lines that will utilize both lead and lead free water soluable solder pastes. I have read some discussion about change-over from lead to lead-free jobs related to machine cleanliness, etc. H

Our company is having issues with our YesTech F1 AOI machine the programs are currently not utilizing this machine correctly. we are have a false call rates of about 5% to as high as 12% of the total number of inspection points. I have started to rep
