What are the production processes of ceramic PCBs?
(I) Laser processing technology
Lasers play a vital role in ceramic PCB processing. Laser drilling has the advantages of high precision and high efficiency, and can meet the requirements of electronic devices and semiconductor components for micropore diameters ranging from 0.05 to 0.2 mm.
Laser cutting also has many advantages. First, it has high precision, fast speed, narrow slits, small heat-affected zone, and smooth cut surfaces without burrs.
(II) Other molding processes
- Tape casting: The advantage is that it can produce large-area, thin-thickness and uniform ceramic substrates, which are suitable for large-scale production. However, tape casting has high requirements for equipment, and the viscosity and fluidity of the slurry need to be controlled during the process.
- Powder pressing: Simple operation and low cost. However, the pressed ceramic substrate may have problems of uneven density and high porosity, which affect its performance.
- Extrusion molding: Suitable for the production of long strip or tubular ceramic substrates with high production efficiency. However, the shape of the extruded ceramic substrate is relatively simple and the dimensional accuracy is relatively low.
(III) LAM process advantages
The LAM process has significant advantages in ceramic PCB manufacturing.
First, the bonding strength between the metal layer and the ceramic is high, up to 45 MPa (the strength of the ceramic sheet is greater than 1mm thick), the conductivity is good, and the heat is small when the current passes through.
Secondly, the thermal conductivity is high. The thermal conductivity of alumina ceramics is 20-35 W/mk, and the thermal conductivity of aluminum nitride ceramics is 170-230 W/mk, which is much higher than the thermal conductivity of the traditional aluminum-based circuit board MCPCB of 1 to 2 W/mk.
In addition, the insulation is good, and the breakdown voltage is as high as 20KV/mm. The thickness of the conductive layer can be customized arbitrarily within the range of 1μm-1mm, and the current can be designed according to the circuit module. The thicker the copper layer, the greater the current passing through.
The high-frequency loss is small, and high-frequency circuits can be designed and assembled; the dielectric constant is very small, and the line/spacing (L/S) resolution can reach 20μm, thus achieving short and thin devices.
It does not contain organic components, is resistant to cosmic rays, and has high reliability and long service life in the aerospace field; the copper layer does not contain an oxide layer and can be used for a long time in a reducing atmosphere.
What are the characteristics of ceramic pcb manufacturer?
- (I) Obvious technical advantages
Ceramic PCB manufacturers have significant technical advantages. First of all, high thermal conductivity is one of the outstanding features of ceramic PCB. This enables ceramic PCB to effectively dissipate heat in high-power electronic equipment and improve the reliability and stability of the equipment.
Low thermal expansion coefficient is also an important technical feature of ceramic PCB. Its thermal expansion coefficient is close to that of silicon chips, which can save labor and materials and reduce costs. At the same time, when the temperature changes, it can reduce the stress caused by thermal expansion and contraction, and ensure the stability of the circuit.
High surface hardness makes ceramic PCB more durable and longer service life. Compared with traditional PCBs, ceramic PCBs are not easily scratched and worn, and can maintain good performance in harsh environments.
- (II) Adapt to a variety of fields
Ceramic PCB has a wide range of application advantages in many fields.
In the field of LED lighting, the excellent heat dissipation performance of ceramic PCB can effectively reduce the temperature of LED chips, improve luminous efficiency and life. At the same time, ceramic PCB has good insulation and high pressure resistance, which ensures personal safety and equipment protection.
In the semiconductor field, the high thermal conductivity of ceramic PCB can quickly conduct heat away from semiconductor chips and improve cooling efficiency. In addition, the low thermal expansion coefficient and high surface hardness of ceramic PCB can adapt to the working environment of semiconductor coolers at different temperatures and ensure its stable performance.
