What Are Circuit Board Assembly Services?

Circuit board assembly services play a crucial role in the electronics manufacturing industry. They involve the process of placing electronic components onto a blank PCB to form a functioning circuit. This process transforms a bare board into a working device. It’s used in every industry that depends on electronics — from smartphones and cars to medical devices and aerospace equipment.

There are three main methods in circuit board assembly:

SMT (Surface Mount Technology): Components are mounted directly onto the surface of the PCB.
THT (Through-Hole Technology): Leads are inserted into holes in the PCB and soldered underneath.
Mixed Assembly: Combines both SMT and THT for boards that require diverse components.

Understanding these methods helps new customers communicate better with suppliers and choose the right assembly process based on the design and function of their product.

Types of Circuit Board Assembly Methods

Different circuit designs and application needs call for different assembly methods. Here’s a breakdown:

Surface Mount Technology (SMT)

SMT is the most common technique in use today. Components are placed directly on the PCB surface, enabling smaller designs, higher component density, and faster assembly. Automated pick-and-place machines position these components with high precision. It’s suitable for compact and high-speed devices such as smartphones, tablets, and IoT products.

Through-Hole Technology (THT)

THT involves placing components with wire leads through pre-drilled holes in the PCB. The leads are soldered on the opposite side. This method offers greater mechanical strength and is often used for components that experience physical stress or need a strong bond, like connectors or transformers. THT is common in industrial and automotive PCBs.

Mixed Assembly

When a PCB requires both surface-mounted components and through-hole parts, a mixed assembly approach is used. It’s often found in complex designs, especially when different voltage levels or mechanical supports are needed. Mixed assembly offers more flexibility but also requires advanced equipment and careful coordination.

Dual In-line Package (DIP) Assembly

DIP is a specific type of through-hole assembly method that uses components with two parallel rows of pins (leads). These components are inserted into matching holes on the PCB and are often hand-soldered or wave-soldered. DIP is commonly used for ICs (integrated circuits), microcontrollers, and programmable logic devices during development or low-volume production. While not as compact as SMT, DIP is easier to prototype and replace, making it useful in educational, industrial, and repair applications.

Turnkey vs. Consigned PCB Assembly: What’s the Difference?

When working with an assembly partner, it’s essential to choose the right sourcing model:

1. Turnkey Assembly

In a full-turnkey model, the assembly provider takes care of everything. This includes sourcing components, manufacturing the PCB, assembling parts, testing, and delivery. It’s a hands-off approach for the customer and is preferred by startups or teams with limited resources. It reduces management complexity and lead times.

2. Consigned Assembly

With consigned assembly, the customer provides some or all the components. This is ideal for companies that already have components in stock or require tight control over part sourcing. While it offers flexibility, it also requires more effort from the client to ensure timely material delivery.

3. Partial Turnkey

A hybrid of the two, partial turnkey services split responsibilities — the customer supplies some components, and the assembler handles the rest. This balances control and convenience.

At Best Technology, we offer both full turnkey PCB assembly service and consigned assembly. All of our components are sourced from authorized distributor or digikey, mousers, find chips and so on. We have established stable bussiness relationship with them, so that we can get the best price and shorter lead time.
