Hi all What adhesive you recommend to catch thermocouple to the board? (resistant to high temp and easy remove from PCB) Thank Frederic

NADCAP and thermocouple calibration

And to my knowledge, there is no calibration of Thermocouples. They can only be checked for their continuity and resistive value. The question would appear to be invalid.

| Hi | I have been conducting my first reflow profiles. Most of the texts that I have read suggest soldering the thermocouples to a populated pcb. I am finding this very difficult. I have been using a high melting point (Sn5 / Pb95) solder and the

Heller 1706EXL increased thermal cascade on last 3 zones

During production the temperatures on the last 3 zones are approx. 20F higher than the setpoint. The other zones are operating within spec. We checked power, I/O, SSR's, thermocouples, and exhaust, but the issue remains. We did not check resista

Thermal profiling typically requires a profiling kit, this will include a thermally insulated datalogger that follows your PCB through the oven connected to a number of thermocouples which you might affix to your PCB using heat resistant tape or usin

Tantalum caps causing misaligned parts

I once worked for a new branch of a company. We had a board where one of two tants would shift in the oven. When I phoned up HQ because they had ran the board before as soon as I said the product name their guy said "C148 shifts in the oven" He knew

You can contact Heller service by email info@hellerindustries.com to get help with any issue. High Deviation or high process alarm could be due to one of the below reason. A. Blower motor in subject zone is not running – check for air flow B. Heat

Hi mate, no complete info given from what i see, so just some humble comments, mayhaps you review : 1) PCB pad finishing - Copper+nickle plated? coz if so, nickle is a KILLER to good solder wetting. what we did back here, was to HAL coat the nickle

Yup, that seems to be the procedure in the manual. But, it gets complicated, as the head has a rotation, the part has a rotation, and the MA station has a rotation, and it gets pretty confusing to figure out which way to tweak the offset values for
