PCB Assembly For Intelligent Wearing Beauty Mask
We successfully produced a smart beauty mask PCB board for our customer. The
delivery time required by customers is very strictly and almost impossible for us to
complete production. But we finally delivered on time by our hard work. Customer is
very satisfied that we can delivery in such a short time and ensure that all the PCBAs
pass the functional test. They feel thankful for our entire team on handling the
problem in a timely and efficient manner.
Production Introduction:
Mask beauty instrument is an advanced high-tech beauty project. Use full-spectrum
strong light, directly irradiated on the surface of the skin. It can penetrate into the
deep layer of the skin, remove all kinds of defects on the skin. The photonic skin
tenderizer adopts new technology, comprehensive software upgrade, high intelligent
control system, automatic identification of different color spectra. It is more strictly
control of the output of specific spectra, better skin tenderness effect and more safe.
Different color photons head that respectively for different skin defects, skin
tenderness effect is more prominent.
Production Process：
This product consists of two parts - main control PCB board and face mask circuit
board
The face mask circuit board is FPC ( Flexible PCB) and material is Polyimide. Surface
Finishing is OSP (also known as the oxidation resistance). The panel way is V-CUT or
stamp holes.

Control board material is FR4, LF-HASL surface finishing and panel way is V-CUT.
Production Difficult：
Technical difficulties in the preliminary work
（1）Main control chip need do program burning, so we need prepare test tooling,
test environment and test way.
（ 2 ） As face mask board is flexible PCB, so assembly tooling is necessary for
components assembly.
Technical difficulties in medium-term work
（1）The face mask board is assembled by a kind of 5050-packaged four-color LED
that needs to be baked at 65 degree for 12 hours prior to remove the water vapor in
the LED lamp and prevent the burst from appearing after assembly.
（2）The face mask material is flexible circuit board. When the mask board is placed
on the load plate, it will appear uneven when it passes through the re-flow oven. As
this board is a one-sided assembly board, we find a way to solve the uneven problem,
it’s to use double-sided high temperature tape on the load board to deal with it.

（3）Confirm the polarity of components is main job for control board.
Technical difficulties in the later work
1) Testing of mask board : The difficulty is to prepare the test equipment and test
conditions, the height of the test probe, the selection of the test probe and
connection between mask board and the test fixture, etc.
Performance Test for Face Mask Board
2) Program burning and performance test:
The JIP test tooling wires connection is a very importance and difficult matter as it
really has many wires. To burn main control chip is a key point.
Controller Board JIP Test Tooling
Directions:
This product we combine the controller board and mask board together.It needs to
connect 12V power for controller board after it programmed . The control board

contains four key switches, the corresponding function is ‘mode’ ‘increase’ ‘decrease’
‘reset’, red light is to promote cell regeneration, improve the swelling after operation.
The effect of blue light is to treat acne on the skin and be friendly to sensitive
muscles. The effect of IR is to reduce inflammation and promote the healing of small
wounds. This product is safe, high temperature free and easy to operate without
additional training on how to use.
Our Advantages
We have many years of working experience in the PCB and PCBA industries. After
continuous improvement, we now have a complete management and production
inspection system.
ERP System
We use ERP system from the entry of all data to the material access management,
real-time updates until inspection. The ERP system effectively increases the integrity
and uniformity of data storage, helping employees to simplify work processes and
improve work efficiency so as to avoid recurrence of problems. Scientific and
reasonable management of various resource integration problems encountered
during the operation of the enterprise, helping our employees to provide customers
with satisfactory products and services.
Strict IQC Inspection
Inspection and acceptance of parts must be carried out in strict accordance with the
requirements of this regulation.
1. During IQC inspection and acceptance, anti-static gloves are necessary and you
can't touch the IC chip with your bare hands to avoid the phenomenon of
electrostatic breakdown of the product.
2. Measure weather capacitance, resistance and inductance are consistent with the
BOM value . Whether the LED light color is consistent with the BOM. Check whether
the PCB Mark points are symmetrical or not.

Component Procurement Control
Purchasing personnel establish a comprehensive evaluation system for suppliers
creditworthiness, performance, after-sales service capabilities and material market
price conditions and trends according to the company's necessary. In order to choose
a reasonable price, reliable quality and high-quality service providers. Establish a
long-term strategic cooperative relationship with them to control the quality of
components from the source. Effectively control and track the entire process of
procurement logistics and capital flow to ensure the normal production and
operation of enterprises.
Professional testing equipment
Our company is equipped with professional testing equipment to provide product
quality assurance. In the early stage of production, the pin gauge and V-groove depth
tester are used to test the PCB and the LCR meter is used to test the components. At
the end of production, we use AOI to inspect welding problems and perform finished
product inspection according to the tools provided by customers. Guarantee to
provide customers with qualified products in the end.
Protection of intellectual property
Our company has a clear intellectual property management policy and goals and
resolutely implements quality management system standards. Now has obtained the
certificate of intellectual property management system certification.
