2:Characteristics and layout of aluminum substrate
I. Characteristics of aluminum substrate
1. Adopt SMT;
2. In the circuit design eucalyptus for thermal diffusion is very useful disposal;(suitable for LED lamp board, high heat electronic board)
3. Reduce product operating temperature, improve product power density and reliability, and extend product service life;
4. Reduce the volume of the product, reduce the hardware and installation cost;
5. Replace fragile ceramic substrate to achieve very good mechanical endurance.
Layout of aluminum substrate
Aluminum base copper clad plate is a kind of metal circuit board information, which is composed of copper foil, thermal insulation layer and metal substrate. Its layout is divided into three layers:
Line Layer: equivalent to the copper clad PCB, line copper foil thickness loz to 10oz.
Dielcctric Layer: insulation Layer is a Layer of low thermal resistance thermal insulation data.Thickness: 0.003 "to 0.006" is the core site of aluminum base copper cladding, UL certified.
Base Layer: a metal substrate, usually aluminum or optionally copper.Aluminum base copper clad plate and traditional epoxy glass cloth laminate.
PCB aluminum substrate is composed of circuit layer, thermal insulation layer and metal substrate.Circuit layer (that is, copper foil) is usually etched to form a printed circuit, so that the components of the components are connected to each other. Generally, the circuit layer requires a large current carrying capacity, so thicker copper foil should be used. The thickness is usually 35 microns to 280 microns.Thermal insulation layer is the core skill of PCB aluminum substrate. It is usually made of special polymer filled with special ceramics. It has low thermal resistance, excellent viscoelastic function, anti-thermal aging ability and can accept mechanical and thermal stress.T-101, t-111, t-112, t-113, t-114, t-200, t-300, t-400, t-500, t-600 and other high-function PCB aluminum substrate thermal insulation layer is the use of this kind of skills, so that it has excellent thermal conductivity and high strength electrical insulation function;Metal bottom layer is the support component of aluminum substrate, demand has high thermal conductivity, usually aluminum substrate, can also be used copper plate (copper plate can provide very good thermal conductivity), suitable for drilling, punching shear and cut and other customary mechanical processing.PCB data has advantages that other data cannot compare.Suitable power component surface mount SMT public art.No radiator, greatly reduced volume, excellent heat dissipation, excellent insulation and mechanical functions.
3:Product Feature and Application
Excellent quality and high Tg value so products can be used for military fields and aerial fields and illuminating fields and home appliance and LED light
4:Payment Terms
TT/Western union
Vacuum wooden box with pallet
Q: What is needed for PCB PCBA quotation?
A: PCB: Quantity, Gerber file and Technic requirements(material,surface finish treatment, copper thickness,board thickness ,...)
PCBA: PCB information, BOM, (Testing documents...)
Q: How can we ensure our information should not let third party to see our design?
Intech: We are willing to sign NDA effect by customer side local law and promising to keep customers data in high confidential level.
Q: How to get the PCBs?
A: For small packages, we will ship the boards to you by DHL,UPS,FedEx,EMS. Door to door service! You will get your PCBs at your home.
For heavy goods more than 300kg, we may ship your PC boards by ship or by air to save freight cost. Of course, if you have your own forwarder, we may contact them for dealing with your shipment.
Q: Will you allow me to put several part number together into one panel?
Yes, this is usually happen in we factory, this way can help customers reduce some cost and to a certain degree, it can help reduce some assembly cost.China Double Sided Metal PCB
