Kev, You seem to have a very good knowledge of your process and can convey it clearly and precisely. My advise to you is to dis-regard the BS most of these guys churn out and follow your own gut. They will ask a s**t load of irrelevant Q's in some fu

Kev, I looked up records of various hollis machines with 3 preheat zones. and with progressive preheat temp. of 300 400 and 500 with a speed of 3.5ft/min the topside board temp was 120C before entering the wave. the preheat elements were infrared. W

Kev, It looks like you have a preheating powerplant and you still only get the board up to 85 Deg. This indicates that the preheating is out of calibration or the range settings might be very wide (Fex the preheat elements shut down at 500 and go ba

I am having problems achieving correct pre-heater temperatures with our Hollis solder wave. Our original "Verification Golden board" program uses a conveyor speed of 5ft per minute and pre-heat temps of 300, 350, 400 respectively. Our "golden Board"

Hi Lads, Thanks for all of the replies. To answer a few of your questions..... My wave is a Hollis PT500N. It has 3 zones of pre-heater rod elements. Each individual element (601195-01) is 500 watts. There are 16 elements per zone so 8 Kw per zone.

No matter in selective soldering or wave soldering process, higher pot temperature and longer wetting time can increase IMC thickness and joint strength(reliability), but as Daivf said, you need to care if the DIP component and bare PCB was damaged b

Most select solder machines I've dealt with use conductance sensors to detect solder.

It is usually done differently. Sensor is in the solder. Once solder becomes goes below the sensor, it triggers you need to add. I believe it measures temperature rather than distance.

Hi, We are facing solder ball problem in manual soldering process (between wire and terminal). we are using no-clean solder (63:37)and temperature setting in iron is around 400 Cel. Can any one suggest me how to solve this problem Any thoughts would

Is this for a Selective Solder? If so what size nozzle do you run. I run at 315 C most of the time. You can speed up your process time and still achieve good solder fill.
