My requirement is to clean flux from PCB after wave soldering. I found information that TCE is harmful to enviroment and human health.

But my doubt is that is it harmful to electronic components in any way. Does it cause failure of electronic components ?

It melts many plastics but not harmful to electronic components. to use it properly you need a vapor degreaser.

Yes it is used for PCB, I have used it in the Automotive Service Industry for many uses. Most popular as a Brake assembly cleaning agent. It is popular today due to its low FLASH POINT, unlike other solvents that contain Heptane, Xylene etc thease have a #4 FLASH POINT. It was first made by the Dow Chemical Co. in 1961. I have enclosed some detailed information on Trichloroethelene Boils at 87.3 Celsius. C(9/5)+32F= 189.14F. Molecular Formula = C2HCI3. Structual Formula = CIC=CHCI.
