PCB Assembly
We provide full solutions for PCB assembly from product concept to production, and support in electronic design, mechanical design, tooling design.We have built cooperation with over 10 strategic suppliers, involving PCB, ICs, Semiconductors, Passive Components, Connectors, metals, plastic and custom-made parts. It’s possible to select production either in China or in Europe to meet the client lead time needs on different cost basis. We almost realize all manufacturing & assembly service in electronic field, from Wire bonding, SMT, DIP, through hole soldering, Function test to Finished product assembly.We don't limit the MOQ(Minimum Order Quantity), including samples, small quantity, big volume.

An electronic component is any physical entity in an electronic system used to affect the electrons or their associated fields in a manner consistent with the intended function of the electronic system. Components are generally intended to be connected together, usually by being soldered to a printed circuit board (PCB), to create an electronic circuit with a particular function.

For purchasing, this process starts when engineering sends them a bill of materials (BOM) for a new design.

To Start With: Bill of Materials (BOM)

A bill of materials (BOM) is a comprehensive list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts, and the quantities of each required to create a product, as well as instructions required for gathering and using the required materials. It can be understood as the recipe and shopping list for creating a final product. The bill of materials usually appears in a hierarchical format, with bottom level showing individual components and materials and the highest level displaying the finished product. The bill of materials explains what, how, and where to buy required materials, and includes instructions for how to assemble the product from the various parts ordered.

Request for Quote(RFQ): What to provide?

Once you have completed your BOM, you are ready to move forward to request for quote(RFQ). A complete BOM should include essential items for PCB assemblers, including part number, manufacturer name, reference designator, quantity, description, case/package, SMT method, top/bottom, points/footprint, and BOM level.

Why Us?

We are not simply middlemen, brokers, or a rep. We take responsibility for the entire supply chain process from design to final delivery of the product, in whatever stage of completion is required by our clients. This allows short staffed procurement departments to focus on other aspects of their primary responsibilities.

Integrated Circuits (ICs)

An integrated circuit is a set of electronic circuits in a single chip incorporated together to perform a specific function.Integrated circuit (IC) sometimes called a microchip. It is a wafer of semiconductor material (usually silicon) on which multiple transistors, capacitors and resistors are fabricated.

Discrete Semiconductors

Discrete semiconductors perform basic functions in electronic circuits, such as rectification (diodes), amplification (transistors) and switching (transistors and thyristors). They typically have two or three terminals.

Passive Components

Passive Components that are capable of affecting the flow of an electrical current, but don’t generate, amplify or control it.
The passive component provides attenuation of an electrical signal instead of generation or amplification. It consumes energy but doesn’t produce or control it. Resistors, capacitors, inductors and transformers are the main passive components used in electronics.


Connectors, the electromechanical devices used to establish electrical connections or optical coupling between circuits.
Connectors are present in almost all electrical applications, they are used in power, telecommunications, audio, video, computing, embedded systems, automation, transportation, ATE systems and lightning applications just to name a few. Connections may be permanent or removable. In every coupling there is generally a "female" (socket, receptacle) and a "male" (plug) that mate together. In their internal construction connectors are formed by contacts or terminals and a dielectric which are held together by the connector’s package or case.

Circuit Protection Components

The circuit protection device is an electrical device used for preventing an unnecessary amount of current. Circuit protection device can become damaged to save other components of the electrical circuit. Circuit protection devices can be either semiconductor (like TVS diodes, circuit protection ICs, etc.) or non-semiconductor (like fuses, PTC Resettable Fuses, gas discharge tubes, etc.)
