If the sensor can survive the 200C in the molding machine, then could it not survive Pb-free soldering? Maybe not convection reflow, but it should be able to survive vapor-phase reflow. I would control solder height by controlling the amount of paste

100 sec.). If I keep TAL closer to where I like it to be, peaks are all low; around 200C to 205C. If I can't find a happy medium between TAL and PEAK, what should I consider doing?

What solder alloy are you using at the moment which is coming to the end of its limits ? Normally in general for safe operation of an alloy we don't like to recommend any operation temp that is higher then two thirds of the solders melt point, but th

Brian, Since the change, I have seen numerous instances of extra zeros being added to numeric values, typically those of 3 (original) characters or more. Case in point, a contribution by our friend Mr. Fish that I have cut and pasted: "The steadfa

1) Do people always bake, sometimes or never? Does this depend on whether MS sensitive components are near the rework site? If a BGA is to be removed and reballed, baking is a no-brainer. Sometimes, based on the proximity of the MS components. >2)

| Hi All, | Any one experince BGA-chipset warp about 10-15mil after removing | from PCB? | FYI, the rework temperature for preheat was 170C from room | temperature about 30 seconds, & BGA was removed at temperature | between 190-200C. | Thankyou.

You need a nylon with a heat deflection temperature [heat distortion temperature] - 0.45MPa ( C ) similar to your reflow peak. The HDT of the nylon in your connector is probably ~200*C. For more, look here http://www.tycoelectronics.com/environment

Hi, Has anyone had any experience with lead free Sn-8Zn-3Bi solder paste? Apparently in Japan it's becoming popular because it's got a melting point of below +200C. Can anyone confirm that, or does anyone have experience with it? Regards, Grant

I have a BTU International VIP98 reflow oven, running WINCON Version 2.00C on Windows 98. The light tower only lights green when the oven reaches temperature, and the other colours never light up. Do you know how to set the other colour lights to tu
