Since the thick film ceramic pcb possesses many benefits then how to make it.
Thick film ceramic pcb.
If it s possible in thin film chances are it can be realized in etched thick film at a fraction of the price.
The conductor is silver or gold palladium and was printed on ceramic substrate.
Our precision etching technology pushes thick film ceramic substrates to a best in class position offering the tightest tolerances and the highest performances rivaling thin film capabilities.
B thin film ceramic board.
Using this technology the thickness of conductor layer exceeds 10 micron more thick than spurting technology.
Typically thick film circuit substrates are al 2 o 3 alumina beryllium oxide beo aluminum nitride aln stainless steel sometimes even some polymers and in rare cases even silicon si coated with silicon dioxide sio 2 most used substrates for a thick film process are either 94 or 96.
They are characterized by a resistive layer on a ceramic base.
Thin and thick film resistors are the most common types in the market.
Normally the thickness will be at least exceeds 10 miron um around 10 13um more thick than spurting technology in thin film ceramic pcb.
What are thick film circuit boards.

What are thin and thick film resistors.
The metal deposition methods used in vacuum processes and the flexibility that can be achieved in terms of thickness and type of metallization in particular really set thin film technology apart from printed circuit board technology.
The size of the common ceramic substrate is 114 114mm.
The naming originates from the different layer thicknesses.
A typical thick film process would consist of the following stages.
Although this type of fabrication technology is optimal to large scale ceramic pcb manufacturing and features relatively high assembly base number its application is limited due to high cost.
