Hi, Could you guys verify my BTU VIP98N oven settings for lead free process. At the moment as my standard profile im using these settings 140 160 180 207 205 220 257 same temps for bottom and speed 50cm/min. Has anyone got same oven and could

Hi Aj, Recommended Immersion gold thickness would be 3-5 Micro inches over 140 -200 micro inches of Nickel. Thicker Immersion gold than 5 micro inches can cause solder joint embrittlement. Gold readily dissolves in molten solder and will be present

I can't help you much there, but I do have a couple of manuals for a TDK RX-40!! Ha! That machine brings back memories....operator forgets to lock a feeder down, and in about thirty seconds, you have 140 nozzles with the tips ripped off. Ahhh...those

I think you are too hot out of the gate as well as too slow on conveyor. I think settings similar to 130, 140, 150, 160, 230, 240, 260 and conveyor speed at about 28 or 29 IPM would be more realistic but it depends on your paste and oven config/zone

You should do some testing what temp you really get. Solder will melt 260~300ºC. Back to the initial question, CEM-3 is a bit harder to buy and has not many varieties. Go for FR4, you can go for a higher Tg then the common 130ºC. There is also 140,

Hi, Detergent/saponifiers have indeed the potential to tarnish aluminum. This is due to the high alkalinity of the chemistry (pH 10-12). Things you can do to minimize the effect is: A) Limit the exposure time of the Al with the chemistry. B) Reduc

We are currently experiencing with our SMD Solder Reflow Equipment on Shooting-Up Zones (Zones 3,4,5,7 & even Cooling Zone). PV exceeds about 5-10 degrees with the SP. (ex: SP=140deg, actual PV = 145deg & higher). Our equipment undergo a monthly prev

I'm attempting to perform power analysis on my target, which operates at 3.3 volts. The average current while running is around 140mA without the resistor. With a 5V power source, I utilized a 10Ohm resistor as a shunt resistor. The shunt resistor w
