I used to just follow up profile development with a single pass with a MOLE, one thermocouple in air. I'd keep that profile as a baseline, and have the operators run the MOLE through prior to production and compare the results to the baseline. I foun

I agree, I have been doing this for years also. Never found anything that the oven wasn't already telling me. I will however be investing in the KIC 24/7 constant monitoring device soon. Price isn't too bad for what you get. Customers like to get a w

Does it give any more info about the error? Is this in the stage after you've hit run, it says "initializing" and it is counting up on the screen? Usually it gives a little more info, although it can still be cryptic. I have run into it stopping w

Yeah, getting water into electronics, especially when there is power on, even just battery power, is REALLY bad business. I was rather surprised that you only lost part of the memory if water got up to the board. It may be fixable, but you may have

I have always understood that on boards (or circuits) operating over 900 MHz, No Clean fluxes are to be avoided. Apparently the residues left behind, while non-conductive and non-corrosive, will change impedence of the circuit. It may be a possibil

To get you started you might want to look at http://en.wikipedia.org/wiki/RoHS I think it's as good a place as any to get started. It has the basics explained in a straightforward manner. At the bottom of the page are external links they probably

Hi, What is the expected reject rate for capacitors on a CP643 machine. I estimate that we are dumping around 1 in 20 on average. I have played around with lighting levels,vision types etc. Nozzles are in mint condition. Can anyone offer any advice

Feeder is brand new. (Checked cal. even though it was new) Lighting is good. Machine is in perfect cal. Nozzles are brand spankin new from Fuji. I was able to lower the reject rate considerably by playing with the offset and gain. I am placing caps

Hope that your PCB is supported evenly, I mean really plane to the conveyer rail. If not this may warp the PCB upwards, causing fiducials to be identified not accurately. Also I suggest you to check Mark Info of the fiducials and have a look at the t

I talked to someone regarding the Biral oil and they said that they have had a problem with it "jelling up" when exposed to oxegen. Has this been a problem for you as well? I ordered some Stabylyn 773ND from Vitronics. I hope this stuff works for 57.
