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"

If you are concerned with the actual temp of your pre-heater verses what the machine's display "says" the temp is, use a calibrated digital thermometer and place the thermocouple probe inside the pre-heater and next to the machine's thermocouple for

So others can solder the same board and part but you can't. Dipping the legs in flux doesn't help. Then it's either your pre-heat or wave. Measure your pre-heat and compare to others or flux mfger. Do you have chip wave or something like an Omega

we worked out that the wave soldering cassettes Duratstone material takes alomst 35 degree away from the surface of the pcb, and the speed is already too slow it should be over 1.0 - 1.8 meters a minute but its now already 82 cm a minute, in order to

Hi Thomas, AOI Systems provides very affordable bench top and inline AOI systems for both pre and post reflow. Many customers are purchasing these units for pre-reflow inspection due to the ease of programming and access for pre-reflow adjustments. A

Pin through paste an option?????????????

This connector requires a hole size of 0.055" diameter. A little too large for pin and paste.

I am wave soldering, do I have to change the hole size for solder pre-forms or press-fit?

Various solder metal supplies sell pre-forms as loose individual shapes, usually donuts. The loose performs then are placed on the connector leads. If you have any volume at all, you would want to look at a �shake table� that would vibrate a batch of

We are trying to implement AOI into the mix. One PE wants it Pre-Reflow, to catch and fix the PnP screw ups and the other PE wants it Post-Reflow, because the oven will fix quite a bit of placement offsets and mainly to catch any problems that the R
