1. High Vacuum Environments

The high vacuum environments require a lot of parts with sealing surfaces and leak testing requirements. Suppliers must get very proficient at machining these sealing surfaces to the surface finishes needed. Often times a good supplier will leak tested various systems: deionized or RO water, coolant, oil, clean dry air, helium, and vacuum systems. Interestingly enough, bringing helium leak testing in house vacuum testing for complex parts can become a critical capability for a cnc machine shop in the Semi business to procure.

2. Double and Half Cyclical Business

The “double and half in one quarter” nature of the semiconductor business volume is a problem for lots of companies. The ability to react to the fluctuations through smaller order sizes and maintaining excess capacity and space to absorb sudden upswings in business is paramount. By having a large warehouse, extra CNC’s, night shift capacity, expanded cleanroom, assembly cells, etc these swings can easily be accommodated. Some parts require managing and maintaining “machine ready blanks” or partially finished stock of long lead components.

3. Cleanliness Requirements

The cleanliness requirements constantly get more stringent. The best suppliers will have inhouse cleanroom with UV and bright light inspection for inspecting for particle contamination. Upgraded & installing a new sweep frequency ultrasonics cleaning unit can also be a huge asset. In house supply of monitored high purity/resistivity RO water is great for in house cleaning. Mimicking the OEMs detergent chemistry, times, temperatures and techniques in the wash sequence. Not many companies in the states to get qualified to OEM vacuum gas purity cleanliness level for manifolds. By moving towards getting qualified over the next couple years to be able to clean parts to a “vacuum clean” level with residual gas analysis to prove the cleanliness levels are being met, the best suppliers will become an even better partner for their OEM customers.

The Semiconductor industry certainly has its own challenges for CNC Machine parts manufacturers and assembly houses.  By mitigated the cyclical business nature, understanding high vacuum requirements and putting effort into creating centers for maintaining customer required cleanliness, great shops like PEKO will continue to be great partners for the semiconductor industry.  For more information, click below or contact me direct: Scott Baxter, 585-647-3010
