With the continuous development of the time,people’s living standard improve continually.The car has been a very important vehichle in our life.Global automotive electronics industry has accessed to a new round of capital and technology integration.The automotive circuit board continually presents a variation trend.Summerized into bellowing types: First,high energy/strong electricity
1. high energy:the driver module’s practical power IGBT of hybrid electric vehicle and electromobile will produce 1000 to 2000 quantity of heat.
2. New style board:the medium and small power transducer speed regulation device,high power transducer speed regulation device,contravariant device induction heating apparatus,reactive compensation,active power filter,the communication power supply must have the ceramics copper-clad plate,aluminum silicon carbide substrate material.
3. Base on led illuminating system
4. Frequency controll device
5. Strong electricity controller,
Second,automobile circuit board high density interconnection(HDI)
1. Unique advantage:the size,layers of automobile circuit board has been reduced;inlayer wiring vacancy;reduce the risk of solder bridge;advanced hot micropore;
2. Laser light drill micropore apply;
3. High density interconnection and special type pcb(back board,high frequency board,metal base board,thick copper foil board,photoelectricity pringting board)
strong electricity/thick copper plate technology:single and double thick copper-clad plate;copper plating and copper etching;electric conduction(overbiting,bonding)
external wire/copper thickness and etching technology:green printing ink overbiting process;
thick copper-clad plate;printing and etching;thick copper and plug-in board;machine manufacturing(wiring,punch,water sprinkling,laser)
Fifth,automobile circuit board use environmental protection material
1. implement green design,green production:according with ROHS standard;
2. Lead free manufacturing process:according with the lead-free reflow soldering technology of the highest setting temprature260℃.
3. According with halogen-free request.(it’s ROHS environmental requirement)
