Lighting application of PCBA
PCB assembly service provides a universal base for a variety of
high output LED applications. LED lighting solutions are rapidly
evolving across industries where low power consumption, high
efficiency and impressive light output are important. These LEDs
gain more functionality when integrated with the PCB. PCBs
facilitate expanded usage of LED lighting solutions, especially
including displays and indicators.
Some of the most common applications for PCB LEDs within the
lighting industry include the following:
1. Telecom Industry: Telecom equipment often uses PCB to control
its LED indicators and displays. In this industry, lightweight and
durable PCBs tend to be advantageous, mainly because of the
mechanical density in the industry. Aluminum PCBs are often used in
telecom lighting applications due to their better heat transfer
properties than FR4 variants.
2. Automotive industry: PCB LED displays are commonly found in the
automotive industry, especially dashboard indicators, headlights,
brake lights and advanced panel displays. The industry particularly
favors PCB LEDs due to their low manufacturing costs and impressive
durability, which increases the value and lifespan of vehicles.
3. Computer Technology Industry: PCB-based LEDs are becoming more
common in the computer technology industry, commonly found in
desktop and laptop monitors and indicators. Due to the thermal
sensitivity of computer technology, aluminum-based PCBs are
particularly suitable for LED lighting applications within
computers.
4. Medical industry: Lighting tools are very important In medical
applications, especially in surgical and emergency applications,
large light can help improve the visibility of doctors. In these
applications, LEDs are often the lighting method of choice for
their power and small size. PCBs are often used as the basis for
these applications, especially aluminum PCBs, which have a longer
lifespan and offer better heat transfer capabilities than other PCB
types. In this way, PCB LEDs ensure durable medical devices that
can be reused in a variety of medical settings.

FAQ
Q: What is your inspection policy? How do you control the quality?
XHT: In order to ensure the quality of PCB products, flying probe
inspection is usually used; electrical fixtures, automatic optical
inspection (AOI), BGA parts x-ray inspection, first article
inspection ( FAI) 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 long is the shelf life of the PCB board and how should it be
stored?
XHT: 25℃ / 60%RH is recommended when the PCB is stored. The plate
itself has no shelf life, but if it exceeds three months, it needs
to be baked to remove moisture and stress, and it should be used
immediately after baking. It is recommended that the pieces should
be loaded within 6 months of storage to reduce the phenomenon of
rejection and explosion. |
Q: Are my files safe?
XHT: Your files are held in complete safety and security.We protect
the intellectual property for our customers in the whole process..
All documents from customers are never shared with any third
parties.
