2. Analysis of reasons a) Conductive rod is poorly conductive b) Cathode plate is poorly conductive c) Conductive seat is in poor contact, resulting in uneven film thickness d) Inhomogeneity in bath temperature e) Local temperature of oven is too high 3. Improve preventive measures a) When the clip is removed, the conductive rod is removed from the membrane to ensure that it is not loosened b) The cathode plate is adjusted so that it is evenly distributed c) The conductive base is polished d) The cycle is improved, and the circulation is increased e) The oven door is adjusted.
