1. Incoming Quality Control (IQC)
The function of incoming quality control (IQC) is to ensure the quality of material inventory. After the demand on material order is released, the materials supplied by the supplier need to be checked for acceptance. The departments mainly involve the purchasing department, warehouse, quality department and engineering department. The warehouse clerk informs the quality supervisor to inspect the materials (material inspection form), and the quality supervisor shall count the quantity and check the materials (IQC inspection report)-qualified materials (in-warehouse); unqualified materials (special procurement/return). The engineering department confirms the first material and supervises the quality specification during the batch production process, and feeds it back to the quality department and the purchasing department (IPQC audit record form and quality feedback notice) to improve the yield rate of process products and reduce costs.
2. In Production Inspection Control (IPQC/PQC)
