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.

What is PCB Components Sourcing?

PCB Component sourcing refers to the purchasing the PCB components to be assembled onto the printed circuit board.Component sourcing can be done in many ways.You can have the suppliers purchase components from authorized and reliable distributors of their choice and deliver to you by order.You can also recommend a distributor where the supplier can source the components from and deliver to you.Still, you can opt to source for some components and let another supplier source the rest.Component sourcing can either be done locally or from abroad. International component sourcing usually takes around 5-10 working days depending on the duration of customs clearance.Local sourcing, on the other hand, takes a shorter time. It is therefore preferred, especially if all the required components are available because it helps save on time and production cost.
