From various research I also found the HT500 series was/is being manufactured by Saint Gobain (part number M797). The product is still available through various distributors, though I imagine the quality issues will still be present. The quality issu

This is an interesting task you are faced with. If I understand you problem you need to double your throughput ? Is that correct ? If that is the case there are so many more factors to consider besides your equipment, adding more shifts etc. First o

Hello I made some test on different oven and problem still occurs. The only progress is that with diffrent thermoprofil ( Ramp to Spike instead of Ramp- Soak- Spike skewed components appears at 1 % of produced parts). With Ramp - Soak-Spike we have p

Many thanks for your reply. We would like to clarify two things; 1. We have recently purchased a vision system with oblique viewing facility to rotate the camera with 40x magnification, which we find useful to inspect fine pitch components . 2. Wh

Hello Just wondering if anyone has done trials on how long you can leave paste (tin-lead or pb free) on a board after you have printed it before it starts going 'off'? Thanks Chrissie FYI - have searched and found the 'pasting ahead' thread - jus

I have seen a method used where the pins on the connector are of the same materials as the thermocouple and the connector is connected via single strand wires of the same material to the PCB however the wires were spot welded to bare copper pads to r
