You can keep only the 5th zone as the reflow zone. And lower the first two zones to keep a good ramping rate. Meanwhile,please note the ting temperature in software or control panel is not the exact temperature in your PCB, you'd better get a KIC or

thomas, why isn't it process control, you cant just think that because you've set up your machine properly ( pot temp, wave height, pre-heat etc etc )that everything is going to be ok, there are other factors that you wont find with wave riders or

You mean you don't pull all of your thermocouples out of the ovens once a year and send them out for calibration? - lol Tough question. You have a calibrated datalogger. (I assume) You have an oven with preset zone temps, each zone controlled by a

Good answer slthomas! This has got to be the biggest misconception out there. To perform SPC on a wave process you must first perfrom DOE to determine the critical parameters and or control limits. For example you will need temp reading devices tha

I�ve been lurking on the forum for a while so I will take a stab at this, mainly because there is no answer I take it that you have a variety of boards being produced at the same time and are in fixtures so the conveyors don�t need to be adjusted, a

Guys, So I recently started working for a small CM in Southern N.H. We currently use 2 Magic Chef Mini wine friges to store the solder paste (63/37, RoHS). I've been monitoring the room temp (and humidity) and the frige temps all this week. The pro

There is none, since we don't know your part or temp being used. A heat gun CAN be used to remove parts with no damage, if its controled. You need to look up your part on the manufacturers web site, find the process data (time/temp)the part is desi

RS sell a heat cun that is fully temperature adjustable buy one of them and pre set it to the right temp then put a calibration sticker over the control.

We use a normal off the shelf (Best Buy) mini fridge. As far as the temp readings, I got some USB dataloggers from Omega and stick them in there. Download the data to your PC every couple of weeks (Outlook reminder). I also use these for our Nitrogen

80 degrees F in the Summer. Also, "It is not recommended to store foods which must be kept at below 40� F for safe storage". Obviously we're not storing food, but the point is still valid. jdumont, Thanks for the data. I have a couple of Extech di
