COMPANY PROFILES
Pinsheng Electronics started to provide contract electronics design and manufacturing services in 2008, we are obsessed with providing the happiest manufacturing experience to our customers.

When our founders found it difficult to get technical support and always high-quality products from the manufacturers, they sprouted the vision to provide blissful electronics manufacturing services to others, they rented an old workshop and started the journey.

In over 15 years, with the same vision, we have designed, manufactured, and delivered 5,000+ projects for over 2,000 SMEs. The products are alive to us, not lifeless pieces of stuff.

#Quality Assurance

Key Specifications Quality Control Under Production Process
Our production department start proceed according to:
       -MI (Manufacturing instruction), and strictly follow below
       -PQA ( process quality assurance), to guarantee the quality.


Production Control
#Main Person in Production Workshop:
-Technical Manager
>= 3 years of relevant work experience

-Engineers
>= 5 years of relevant work experience
Be fluent in English
Familiar with PCB circuit layout and design software (Altium, Protel, PowPCB)
Master PCB manufacturing and fabrication process

#Main Production Equipment
About the production equipment, our company has advanced and professional production equipment to ensure good and high quality.

Equipment	Function
Inner and outer AOI machine	It can perform AOI detection on inner and outer layers, confirm whether the circuit is qualified and access.
AVI	Before FQC visual inspection, intercept bad appearance effectively and play the role of double insurance
VCP Pattern Plating line	The electroplating quality is more stable than the traditional electroplating line and greatly improves the output
Ionic contamination tester	This machine is needed in the physics laboratory to test the degree of ion contamination of the circuit board and avoid risks

#Unqualified Control Process
Regarding the management of non-conforming products in the production process, our company strictly follows the "non-conforming product management procedures".

       Quality control department,
       Engineering department,
       Production department,
       QA department,
       Business department
are responsible for resolving problems together.Quality ManagementIQC (Incoming Quality Control)
PQC (Process Quality Control)
First Article Inspection, PQC will go to each production machine for inspection every 2-4 hours (size, appearance).
Quality management of semi-finished products in each process. We will send 2-5pcs semi-finished boards of each shift to the quality inspector until they confirm then continue production.
Operator charge the quality inspection for the subsequently semi-finished boards, sign confirmation after approved. Quality inspector random inspections. Only they are qualified can be handed over to the next process.
FQC (Final Quality Control)
(That is the finished product inspection before shipment), appearance inspection 100%, random inspections of board dimension by batch.
FQA (Final Quality Assurance)
According to the inspection standards of FQC sampling verification, and finally control quality, and then double guarantee the PCB quality.

Test and Maintenance Workshop

Test and Maintenance Workshop

STHL provide custom test service according to client's requirements and products. Usually STHL PCBA Tech
offers a full range of testing service. Including:
*AOI (Automatic Optical Inspection)
* Function Testing
* In Circuit Testing
* Testing Fixtures
* Testing Service
* X-Ray for BGA Testing
* Printing Solder Paste Test
Each board is carefully examined by our dedicated inspection  team using AOI and high magnification viewers.
Using our X-Ray machine, we test PCBs to component level and all wiring is fully inspected and tested. Flash 
testing and earth bonding tests can also be undertaken where required.

Material Management

Warehouse Management
Regarding warehouse management, we will divide different areas according to different customers and place customers' products neatly.
And the warehouse administrator will responsible for managing, and ensure the records for outbound and inbound, we strictly follow the Warehousing Requirement Documents to manage all the goods.

FAQ

FAQ

Q1: What's your monthly capacity of PCB assembly
A: Monthly 140 million points from SMT, 300K pieces from DIP.
Q2: How do you go quality control in PCB assembly?
A: We fully comply with ISO requirements and process in accordance with the Quality Management Manual for order management, production management, and process management, and strictly implement processes such as corrective and preventive measures and change management.
Q3: Can you source parts for me even if no assembly need?
A: Absolutely please provide us with your BOM or a list we will analyze the source make classified packaging attached with labels then send them to you.
Q4: What is your components procurement capability? Which supplier do you work with directly?
A: We have more than 40,000 part models in stock, and provide you with hard-to-get chip supply. Our parts are directly from the top level suppliers such as Microchip, TI, ARROW, AVNET, FUTURE, ELMENT, Digikey...
Q5: How do you go inventory management?
A: According to ISO process warehouse management operation guideline, we observe the principle of first-in-first-out of materials, and control the temperature (constant 25°C) and humidity (40% RH) of the warehouse with strict anti-static. Stock materials are managed separately according to different customers.
Q6: How are EOL (End of Life) materials handled? Is it possible to provide the successful case of replacing EOL material?
1. If EOL happens in the running projects, the agent will send a production stoppage notice (Order & Supply deadline), and then our clients will get notified with our alternative suggestions.
2. For the projects transferred from other production source, we will source alternatives in advanced, or come up with and help our clients to change the design if no exact match alternatives.
3. For other cases, we will try to meet the short-term needs of customers based on our understanding of the market inventory situation.
Q7: Do you provide IC programming and fixture creation?
A: IC programming is available for all of our customers, please provide the guidelines and software, it can be done by IC burner or motherboard burn-in. We can make the fixtures as customers' requirements.
Q8: What test methods do you provide?
A: The boards will go through AOI, X-ray, default circuit testing, function testing in regular, and more testing as required.
Q9: What's the lead time?
A: It depends on the quantity and BOM. For usual small batches, it takes about 3-5 weeks, when it comes to mass production for forecast orders, we will schedule the production about 10-12 weeks before delivery.
Q10: How do you ensure delivery on time?
A: We generally guarantee delivery within 5 days after the material is ready (except for rush orders), our measures include:
1. receiving and verifying the files prior to quotation;  
2. ensuring all the materials get ready on time and be checked at the same time;
3. making PCB boards and stencil according to Gerber first;
4. communicate in time when prototyping is running to ensure that problems are handled on the same day.
