Hello everybody...

I hope somebody could solve my problem with regards to soldering and desolderin a transistor. i'm currently workin on building a s-parameter test board for measuring the s-parameters of transistor. the plan is to hav a single board and make all students put their transistors on the board, measure s-parameters and then take it off. at first i thought solderin wud b good...but wats happening is while desoldering atleast one of the pins is getting broken . and by the time i melt the solder on all the 4 pads having 4 pins in order to remove the transistor, they become cold and i'm not able to take the transistor off...So i was wondering there shud b another way to do it. if nebody could come up with a suggestion, it would b gr8. thanks
regards
chris
