I have been using Vapor Phase for about 5 years. We just started building our first BGA and the reflow profile is the same as most SMT assembly.We build PWA that are 25 layers thick with 0.050 heat sinks. We have done some preliminary X ray and BG

VP does work well for BGA Technology but it is not any great improvement on convection reflow. It has been stated in a coulpe of articles that there is no delta T difference with VP from the surface ofthe board and under the BGA. That is not true jus

In order to program your board, you are not exposed to the operating system. If you want to "talk" to a Windows machine via LAN, you will have to install a communication software either on the Windows machine ( disc access ) or on the Linux machine

We are using a MY19 p/p machine from Mydata running Linux, and we are programming it from a Windows98 station, and goes through LAN to the machine when transferring our jobs. It�s a stable machine and we haven�t experienced any negative sides of runn

Gregory, Thank you for posting the results of running your boards yesterday (glad to hear everything worked out well). I am sure other SMTneters are glad to see the sharing of their information helped. Perhaps others who have used information pr
