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.

FAQ
Q: DO YOU TEST ALL YOUR GOODS BEFORE DELIVERY?
XHT: 1. Our products are all original, and we will test the goods before
shipment by professional machines like KEYSIGHT E4991A and KEYSIGHT
E4980.
2. If The buyer need Test Report, we can send the product to
anthoritative institution such as White horse Laboratories(SZ)
Limited,Global Electronics Testing,etc. |
Q: What are the types of solder mask?
XHT: There are traditional epoxy resin IR baking type, UV curing
type, Liquid Photo Imageable Solder Mask and Dry film solder mask.
Currently, the liquid solder mask is the main type. |
Q: How can we guarantee quality?
XHT: Always a pre-production sample before mass production;
Always final Inspection and test report before shipment; |
Q: What is the difference between the HDI board and the general
circuit board?
XHT: Most of HDI use laser to form holes, while general circuit
boards only use mechanical drilling, and HDI boards are
manufactured by the build-up method (Build Up), so more layers will
be added, while general circuit boards are only added once.
