　　Undoubtedly, a design that is easy to test is easier to handle in production than a casual design. But engineers often hope to incorporate more technology at the lowest cost in the smallest volume, which increases the limitation of contact with circuit boards in online and functional testing.

　　The market has also responded to such issues, with existing software tools capable of analyzing designs, conducting reviews based on the rules specified for assembly and testing equipment, and proposing suggestions to make PCBs easier to produce. If these tools are applicable to your product, it is recommended to analyze each design, at least it can quickly identify where testing contact issues were found, with the ultimate goal of making the product easier to manufacture.

　　Structural configuration that meets high-density requirements

　　High density can be achieved by having a small PCB size, having a large number of circuits on UUT, or both. The title above indicates that the mechanical and electrical structure of the system must be considered to meet testing requirements. The mechanical considerations include:

　　How to support UUT

　　Testing area

　　Multi layer board testing (can the tester perform parallel testing?)

　　I/O connector

　　In terms of electricity, if it is a multi-layer board, which one is more economical? Is it a multi instrument approach or a switch converter with a small amount of instruments? Depending on the UUT structure or the type of instrument required, the answer may not be easy to come up with.
