Deengineering PCB 2

[dino40]

Good day all,
I am presently trying to find a design flaw inside a PCB. It looks to be a trace problem but I need to get inside to see. Does anyone know what chemical will allow me to delaminate the board a layer at a time in order to find this problem without destroying the traces? Any suggestions will be very helpful. Thanks all Dino40

Hi dino40.....if u have FR4 resin material, Aromatic Phenol should be able to serve yr purpose. But do not forget to dilute that with Alchohol....But phenol may need HAZMAt license....Please refer to MSDS(material safety datasheet for it) . To confirm , please refer to chemical dictionary which will give u exact composition of material and other physical & chemical properties like melting point, solvents for the product etc....Feel free to ping me if u need any further help.....
