Now Ceramic PCB has been widely used because of its high thermal conductivity, low CTE, low dielectric constant and chemical erosion resistance.

With the development of chip components and surface mount technology (SMT) in electronics industry, traditional printed circuit boards with organic laminates as based material are developing towards high density, high precision, and high reliability.

Ceramic PCB Types According to PCB Manufacturing Process:

High Temperature Co-fired Ceramic (HTCC) PCB:

The main components of HTCC ceramic substrates are alumina, plasticizers, binders, lubricants and solvents. This mixture will form a green ceramic, which is then calendered and curtain coated. Tungsten or molybdenum can be used as the metal for circuit printing. Next, it is exposed to a high temperature of 1700 OC and baked in hydrogen for 32 to 48 hours. It is then laminated and cut. This is suitable for small size ceramic boards and not for large size ceramic boards due to inappropriate shrinkage tolerances and poor warpage

Low Temperature Co-fired Ceramic (LTCC) PCB:

This is a combination of glass crystals and glass composites. In addition, other ingredients such as binders and non-glass ingredients are added. Then, circuit traces are created using a highly conductive gold paste, which is then treated/baked in an oxidizing gas furnace at 900 OC.

Thick Film Ceramic PCB:

Here, two alternating thick films are applied on a ceramic substrate. One is gold thick film and the other is dielectric thick film, but since gold is expensive, copper thick film is implemented, which is a recognized technology for ceramic PCBs. The stack is then moved into a filled bake oven (copper to avoid oxidation), in which it is processed in nitrogen at a temperature of 1000 Ó C. The dielectric paste is produced from nitrogen.

Application of ceramic PCB:

1- High current bright LED lights and spotlights.

2- Automotive electronics such as power controllers, optical systems, power converters and power conditioners

3- Industrial power equipment such as servo drives, robots, etc.

4- Microprocessor, Graphics Card and IC Array

5- Semiconductor Devices

6- Audio Power Amplifier Based on High Power Transistor

7-Solar battery related circuits, inverters, chargers, etc.

8- DC-DC regulators and power management circuits, etc.

FAQs

Q1: What’s the Aluminum board Thermal Conductivity?
Reply: Usually use 0.8-3W/m.K. If you have special demands, such as COB(chip on board) please feel free contact us.

Q2: Is my PCB Gerber file safe if I send it to you for manufacturing?
Reply: We respect customer’s design authority and will never manufacture PCB for someone else without your permission. NDA is acceptable.

Q3:What is your testing policy and how you control the quality?
Reply: For sample, usually tested by flying probe; for PCB volume over 3 square meters, usually tested by fixture, this will be more faster. E-test will be charged only one time. If flying probe test chosen, such test cost will be recharged for any repeat orders.

Q4: What files should we offer?
Reply: If only need PCB, please provide Gerber File and manufacturing specifications; If need PCBA,Please provide Gerber File, Manufacturing specification, BOM list and Pick & Place/XY file.If you don’t have PCB Gerber file, you can send us the PCB sample and tell us the requirement, we can make it.

Q5: How to contact us?
Reply: You can contact us online, telephone, skype, email, and Whatsapp, Wechat and so on. We will reply to you in time within half an hour.
