Good quality control

In order to let our customer have high quality control, we have build a series quality control system as following, let use PCBA as example as following:
Preparation, Review and Control of Manufacturing Instruction
Heart will evaluate all the requirements after receiving the customers' design data and related document. Then, transform the design datum into manufacturing datum by CAM. Finally, a MI which incorporates the manufacturing datum will be formulated according to Heart's real manufacturing process and technologies. MI must be reviewed after preparation by independent engineers. Before the MI is issued, it must be reviewed by QA engineers and get approved. Drilling and routing datum must be confirmed by first article inspection before issued. In a word, Heart makes ways to guarantee that the manufacturing documentation is right and valid.
Incoming Control IQC
In Heart, all materials must be verified and approved before going to the warehouse. Heart establishes strict verifying procedures and working instructions to control the incoming. Furthermore, Heart owns various precise inspection instruments and equipment to guarantee the capability to rightly judge whether the verified material is good or not. Heart applies a computer system to manage materials, which guarantees that materials are used by first-in-first-out. When one material gets close to expiry date, the system will issue a warning, which ensures that materials are used up before expiry or verified before use.
Process Controls of Fabrication
Right manufacturing instruction (MI), total equipment management and maintenance, strict WIP inspection and monitoring as well as working instructions, all these make the whole production process totally controlled. Various precise inspection equipment including the AOI inspection system as well as perfect WIP inspection instructions and control plan, all these guarantee that semi-products and final products, all reach the requirements of customers' spec.
Final Control and Inspection
In Heart, all PCBs must go through the open and short test as well as visual inspection after passed the relative physical tests. Heart owns various advanced test equipment including AOI Testing, 3D AOI Testing, 3D SPI Testing, X-ray inspection and In-Circuit Testing for finished PCB assembly.
