Thermal Management Cost
Metal core PCB Manufacturer---HITECHPCB is one of the largest PCB fabricators in China, 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.
Chine pcb Manufacturer---HITECHPCB 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 atypical of the high level of technology in the bare boards that we produce.
We are working with alternative suppliers to develop materials and process flows that are equivalent (or superior) to the current standard Laird and Bergquist offerings. Once this is complete, we will be able to offer you a viable alternative that will help to save on the piece price of metal and aluminum core pcbs while at the same time reducing lead times due to widely available MCPCB materials.
Aluminium PCB Heatsink Registration
We have developed a process flow that allows us to utilize our existing multilayer registration system in registering the heatsink 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 heatsink and metal core. These include integrating a variety of different machining tools in the fabrication of our Metal Core PCB. A smooth finish is insured by combining existing CNC machining operations as well as specialized mechanical and chemical deburring processes.
Aluminum Core PCB Materials Lead Time
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. This helps to offset the typical lead times of 3+ weeks for raw materials from Laird and Bergquist.
Browning White Soldermask
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 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.
We have worked with our soldermask suppliers as well as suppliers not traditionally associated with the PCB industry to develop a Super-White soldermask that can withstand not only multiple heat cycles during PCB fabrication and PCB assembly processes, but also while in the field.
