Single chip process, the insulation impedance between channels is less than 800K, the impedance to ground is less than 500K, please help us to analyze. Huiding scheme, lightning pattern, suspected of coating photoresist, development problems, but no problem under the microscope. Don't understand, please share information. I don't understand. When you get the gold coin, pat your ass and go.
