Best Technology is one of the best pcb manufacturers and printed circuit board suppliers in China
Started from Jan 2022, customers sent a Thick film ceramic board prototype design to Best Tech, after numerous manufacturing and testing, they finally have their final-version for this product. So the main purpose of this trip to China is discuss the detaills about thick film ceramic PCB and place bulk orders.
Best Tech have made thick film ceramic boards over 10 years and we are very confident that we cna provide the high quality and best service for you. Below are our capability about thick film ceramic boards.
Substrate can be 96% or 98% Alumina (Al2O3) or Beryllium Oxide (BeO), thickness range: 0.25, 0.38, 0.50mm, 0.635mm (default thickness), 0.76mm, 1.0mm. Thicker thickness such as 1.6mm or 2.0mm can be customized too.
Conductor layer materail is silver palladium, gold palladium, or Mo/Mu+Ni (for Ozone);
Thickness of conductor >= 10 miron (um), and Max can be 20 micron (0.02mm)
Min trace width and space for volume production:0.30mm & 0.30mm, 0.20mm/0.20mm is also okay but cost will be higher, and 0.15mm/0.20mm only available for prototype.
Tolerance for final trace layout will be +/-10%
Both gold and silver palladium is workable for gold-wire bonding, but customer need to mention that so that we will use special silver palladium which is suitable for that artwork.
Gold palladium is much more expensive than silver, about 10~20 times higher
More different resistor value on the same board, more expensive board will be
Normally layers are 1L and 2L (with plated through hole (PTH), and plated material is the same like the one used for conductor), and maximum layers can be 10 layers
Only board with Rectrangle shape can be shipped via single piece, or via panel
Soldermask is also available upon request, working temperature >500 C, and color is semi-transparent
For same stack up, cost lower than DCB, higher than MCPCB
