Preparation, Review And Control Of Manufacturing Instruction

Leadsintec will evaluate all the requirements after receiving the customers' design data and related document. Then, transfer the design datum into manufacturing datum by CAM. Finally, a MI which incorporates the manufacturing datum will be formulated according to leadsintec '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, Leadsintec makes ways to guarantee that the manufacturing documentation is right and valid.

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 equipments 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.

Incoming Control IQC

In Leadsintec, all materials must be verified and approved before going to the warehouse. Leadsintec establishes strict verifying procedures and working instructions to control the incoming. Furthermore, Leadsintec owns various precise inspection instruments and equipment to guarantee the capability to rightly judge whether the verified material is good or not. leadsintec 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.

Final Control And Inspection

In Leadsintec, all PCBA must go through the open and short test as well as visual inspection after passed the relative physical tests. Leadsintec owns various advanced test equipments including AOI Testing, and In-Circuit Testing for finished PCB assembly
