Parts Management

components-store

We have built an effective component sourcing system for low cost electronic assembly. A dedicated team takes care of your PCB components procurement and parts management.

We offer:
Kitted PCB Assembly
Material Inventory Management
Sourcing Your Hard-To-Find Parts
Part Crosses and Substitutions
Unique Global IC Sources
Parts Incoming Check
IC Programming
Electrical Characteristic Analysis
Quick BOM Pricing in 24 hours
Lowest Surcharge Rate

The parts you specified are ordered for each of your assembly needs, if other option exists that is cost saving and reliable, we will offer a alter of choice. A highly systematic and organized, PCB parts purchasing process is followed. We handle the entire logistics of parts and materials, and manage the procurement systems.

Sourcing the best electronic components from high quality vendors and global distributors. Components are procured based on our clients’ authorized suppliers and manufacturers. We have established strong relationships with major electronic components distributors including Arrow Electronics, Avnet, DigiKey Electronics, Farnell Company, Future Electronics, Mouser Electronics, Newark, and Samtec. You are assured of the utmost quality and optimal value for your PCB procurement investment. No substitutions are ever made without your approval.

Normal parts sourcing time is usually completed within 2 weeks from the date the parts are ordered. All parts accepted in inventory storage facilities are tested for quality. A sampling of ICs also are analyzed for Electrical Characteristics.

Function Test

functional-testing

Functional Testing (FCT) is a necessary process within the turn-key assembly services. Functional testing usually is applied after the circuit boards are assembled and AOI & visual inspections are finished.

Functional testing is done mainly to avoid assembly issues including shorts, opens, missing components or the installation of incorrect parts. Customers can deliver a perfect product to their clients.

Functional testers usually use a computer that is connected to test points or a test-probe point in order to perform FCT. We determine if the boards pass or fail based on whether or not the test results meet the specified requirements by operating the software or firmware.

Functional testing is enabled by testing software, often referred to as firmware, and testing instruments such as digital multimeters, input/output PCBs, communication ports. Automated computer-based Functional Testing (FCT) is accomplished by assembly line operators who utilize testing software that interfaces with external instruments to monitor the devices under test.

Early testing enable us to find and correct the component failures, assembly defects or potential design issues at an very early stage and make troubleshooting as quick as possible.
We will preview client’s requirements such as test scope and test instruction, design the test jig if necessary, set up the instruments, and prepare the test report form and design testing workflow.

Equipped with an adjustable DC power supply, a 200MHz digital oscilloscope, a signal generator, an LRC multi-meter and a universal programmer. This covers most embedded system testing. The test results can be either collected by a computer or recorded manually. If the board does not pass the testing, a troubleshooting program will be launched to find the root cause of the failure. A Design For Assembly (DFA) form will be issued by our process engineer and an 8D quality assurance report will be created by our quality engineer. The DFA report will be sent to the customer as a design reference. This will become our quality improvement guideline.

By all these processes, we serves every customer well of their products also their special design needs. This is done by communication and the chasing of perfect product by both sides.

LED’s Definition

led-lamp-2

LED’s Definition

LED is abbreviation of light-emitting diode, it including gallium (Ga),
arsenic (As) phosphorus (P) and nitrogen (N) and other compounds. LED
is a semiconductor device that emits visible light when an electric current
passes through it. Costs less power, more efficient and longer lifespan
than most other light elements. Unlike incandescent lamps, LEDs have no
filaments that can burn out or fail.

LED applies in LED Display/Screen

Indoor LED Displays: SMD Red Green Blue LEDs in one package. Some
outdoor displays do utilize SMD LEDs.

SMD LED Advantages:
Wide-viewing angle
No color shift at extreme viewing angles
Smooth color from short distance

Outdoor LED Displays: DIP Individual Red Green Blue LEDs

DIP LED Advantages:
Weather proof
Extremely bright
Great for longer viewing distance
