Dears,
I will buy about 25k of clean (boards with only ICs and without metallic parts) cell phone boards and will start processing them next week.
I have one important question her about removing or depopulating the components on these broads.
I know that there are many ways to do that:
1- Using heat gun but this way will consume a lot of time
2- Using hot sand bath but this also will take some time and will mix the depopulated components with sand
3- Using HCL or diluted HCL.
For me the easiest way is using HCL/diluted HCL as it will not cost me so much and it will be very quick but seems that the only concern her will be if HCL/diluted HCL will be able to dissolve some of the gold in these BCPs or not.
Some say yes and some say no so need your experience here and there is any other way that is more effective and efficient for processing large quantities
