THERMAL MANAGEMENT COST
Saturn is one of the 50 largest PCB fabricators in North America, and is regularly studying new materials and methods to help save costs. Many suppliers of this technology have developed this specific niche. As a result, their customers must absorb the supplier’s entire overhead via the piece price.
Saturn remains a production PCB supplier with a strong focus on prototyping through production of advanced technologies. However, our facility is also constantly processing higher volumes of standard technology PCBs. As a result, our overhead is spread over a larger number or production panels and projects, allowing us to charge a fair and reasonable price to our customers that are often of the high level of technology in the bare boards that we produce.
We are working on viable alternatives that will help to save on the piece price of metal core aluminum LED Circuit Boards while at the same time reducing lead times due to widely available MCPCB materials. Sign up today for our free thermal management LED PCB webinar.
MULTILAYER PCB HEAT REGISTRATION
We have developed a process flow that allows us to utilize our existing multilayer registration system in registering the heat sink to the PCB accurately to within 5 mils prior to bonding.
We have developed different methods of machining to produce to produce high quality product using metal heatsinks and metal cores. These include integrating a variety of different machining tools in the fabrication of our Metal Core PCBs. A smooth finish is insured by combining existing CNC machining operations as well as specialized mechanical and chemical deburring processes.
LEAD TIME FOR AL CORE PCB MATERIALS
We stock a variety of Aluminum Core PCB material on a regular basis. We also have inventory stocking programs for individual customers to ensure that we have materials on hand for your next order.
BROWNING WHITE SOLDERMASK FOR LED PCB ASSEMBLY
White soldermask is commonly used in LED PCB applications with metal core. A common failure mode for the end OEM is a browning of the soldermask. This browning occurs as a result of the cumulative heat cycles the bare circuit board is exposed to during the soldermask baking and HASL processes at the PWB fabricator as well as reflows and wave solder at the PCBA operation.
SUPERWHITE LED SOLDERMASK
We have worked with our soldermask suppliers as well as suppliers not traditionally associated with the PCB industry to develop a SuperWhite LED soldermask that can withstand not only multiple heat cycles during PCB fabricationPCB assembly processes, but also while in the field.
