Multilayer LED light printed circuit board with Aluminum FR4 PCB Board
Features and benefits
1. The dielectric constant (DK) is low and stable, so the signal
transmission is good without delay.
2. The characteristic of low dielectric loss makes the signal loss
at a lower level, which makes the signal
transmission of the whole equipment excellent.
3. Delamination of copper foil will not be caused by the change of
cold and heat due to the consistency
with the thermal expansion coefficient of copper foil.
4. Immersion gold has excellent surface planarity, particularly
helpful for PCBs with BGA packages or even CSP mounted components
to reduce failure rate during assembly and soldering.
5. UL, ISO certified PCB manufacturing factory.
6. Make delivery on time keeping 98% on-time-delivery rate.
7. Eligible products rate of first production: >95%
8. Experienced sales persons provide skilled customer services.
9. Fast and flexible to save the time of production from prototype
to standard production
Product Show:
1: Membrane switch has below main advantages.
1)Small and portable. Generally a membrane switch is several or
dozens grams, it is quite convenient to carry or disassemble.
2)Aesthetic appearance. It adopts advanced silk screen printing
technology, with special design; We can provide any custom solution
you need.
3)Sealing. To meet customer's unique needs of the program, we can
design the membrane switch to be water- proof, grease proofing,
dust-proof, and static-free...With unique technologies, the
membrane switch can endure a high voltage.
4)Good conductivity. The circuitry is printed with carbon, silver,
copper foil and so on, it can be freely folded, and the resistance
can be limited according to customer's specification.
5)Low cost. Membrane switch is low price, some even costs only
cents. Compare to other electronic components which have same
function, it is exactly cheap price.
6)Long lifetime. The materials are with high isolation, thermal
resistance, fold resistance and rebound resilience. Moreover, the
graphic can not be damaged because of its second surface printing;
The lifetime is usually above 3 years.
7) Tail with or without connector (male or female pin).
2: Product's direction:
To analyze products in current market, most of them are getting to
be short, small, lightweight and thin. Membrane switch is just in
accordance with this design, which is an electronic component that
in combination of art and technology.
3: Type of membrane switch:
Main types: There are many different types and layouts of membrane
switch, its basic function like travel, operating force, life time
mainly depend on type of key and material. The main types can be
sorted as follows:
Membrane switch with flat keys, membrane switch with embossed keys
(rectangle or dome), membrane switch with metal dome or polydome,
tactile or non-tactile, membrane switch with LCD window or embedded
LED, and so on...
