Electronic Circuit Board Fr4 Multilayer Turnkey PCB Assembly Active Prototype IC

Electronic Circuit Board Fr4 Multilayer Turnkey PCB Assembly Active Prototype IC

HDI boards have the following advantages:
1. Can reduce PCB cost. When the PCB density increases beyond eight layers, it is manufactured by HDI and its cost will be lower than the traditional complex pressing process.
2. Increase circuit density, interconnection of traditional circuit boards and parts
3. Promote the use of advanced building techniques
4. Has better electrical performance and signal accuracy
5. Better reliability
6, can improve thermal performance
7. Can improve RFI/EMI/ESD (RFI/EMI/ESD)

Often encountered materials in PCB assembly service

• FR-2, phenolic paper or phenolic cotton paper, paper impregnated with a phenol formaldehyde resin. Common in consumer electronics with single-sided boards. Electrical properties inferior to FR-4. Poor arc resistance. Generally rated to 105 °C.
• FR-4, a woven fiberglass cloth impregnated with an epoxy resin. Low water absorption (up to about 0.15%), good insulation properties, good arc resistance. Very common. Several grades with somewhat different properties are available. Typically rated to 130 °C.
• Aluminum, or metal core board or insulated metal substrate (IMS), clad with thermally conductive thin dielectric - used for parts requiring significant cooling - power switches, LEDs. Consists of usually single, sometimes double layer thin circuit board based on e.g. FR-4, laminated on aluminum sheet metal, commonly 0.8, 1, 1.5, 2 or 3 mm thick. The thicker laminates sometimes also come with thicker copper metalization.
• Flexible substrates - can be a standalone copper-clad foil or can be laminated to a thin stiffener, e.g. 50-130 µm
  • Kapton or UPILEX, a polyimide foil. Used for flexible printed circuits, in this form common in small form-factor consumer electronics or for flexible interconnects. Resistant to high temperatures.
  • Pyralux, a polyimide-fluoropolymer composite foil. Copper layer can delaminate during soldering.
