The Massachusetts based semi-conductor test company has been using various ATS heat sinks, heat sink clips and other thermal management solutions for cooling inside some of its test systems. But market demands called for price reductions by all suppliers. For their thermal management supplier, the OEM singled out three heat sinks for price reductions: ATS heat sinks 1174, 1175 and the 1176.
ATS had originally designed these heat sinks with a good deal of margin in them for the customer’s applications, as they were used on multiple projects. The additional thermal headroom gave the customer what they wanted: a rock solid thermal management design with little risk of overheating. However, as the product and market matured it was clear to this customer that cost reductions would be paramount for their continued success.
ATS thermal engineers approached the customer’s cost reduction methodically. Though the customer’s systems were known and the heat sinks an ATS design, ATS felt that taking a new baseline would insure a clear understanding on the system’s current thermal envelope. An understanding of the problem included understanding the thermal characteristics of the semiconductors involved, the chassis airflow, PCB design, and potential for thermal coupling from device to device.
ATS engineers performed CFD using CF Design from Autodesk’s Blue Ridge Numerics. Thermal analysis was performed using laboratory airflow studies to characterize the available cooling air in the customer’s systems under normal working conditions. ATS work resulted in a design that was still reliable, even though cost and performance reduced. ATS reached all the necessary price and performance targets. Because the customer invested in the long term engineering relationship with ATS, they were able to realize cost savings and product innovation from an existing, trusted advisor and supplier
