Types of PCB Assembly Technologies

Technologies Used in PCB Assembly
PCB Assembly Technologies

Surface Mount Technology (SMT) PCB Assembly

Surface Mount Technology is a method of electronic assembly where components are mounted directly onto the surface of a printed circuit board. SMT assembly allows for smaller, more complex designs and increased production efficiency.

A stencil is used to apply solder paste to the specific areas on the PCB where the components will be placed. Automated pick and place machines accurately position the components on the SMT pads, and the PCB goes through a reflow oven to melt the solder and attach the components.

Through-Hole Technology (THT) PCB Assembly

In the through-hole assembly method (also called thru-hole technology), components have leads or pins that are inserted through holes drilled in the PCB. These leads are then soldered to pads on the opposite side of the board, creating a secure electrical and mechanical connection.

THT connections are generally more robust and durable than SMT connections. This makes them ideal for components that experience mechanical stress or high currents.

Mixed-Technology Assembly (MTA) PCB Assembly

Mixed-Technology Assembly in PCBs refers to the process of combining both SMT and THT components on the same printed circuit board. Mixed assembly leverages the advantages of both technologies to create more versatile and efficient electronic devices.

This flexible and reliable approach to PCB design and manufacturing allows for the creation of complex electronic devices with improved performance, reduced size, and lower costs.

Electronic Component Sourcing Options

Turnkey PCBA Services

The PCB manufacturer provides turnkey components. Opting for turnkey PCBA means you don’t need to source or procure the components yourself, saving both time and effort. OurPCB partners with trusted providers for a fast turnkey PCBA service, so you can be sure you’re getting high-quality parts when you work with us.

Cosignment Printed Circuit Board Assembly

Consignment components are provided to a contract manufacturer (CM) by the original equipment manufacturer (OEM) for assembly into the final product. The OEM retains ownership of these components until they are incorporated into the finished product and sold to the end customer.

Hybrid Assembly Services for PCBs

Mixing consignment and turnkey PCB assembly is a hybrid approach that allows for greater flexibility and customization in the manufacturing process. The OEM provides certain components (consignment) while the CM procures the remaining components and handles the entire assembly process (turnkey).

How We Test Our PCB Assemblies

Automated Optical Inspection (AOI)

Automated Optical Inspection is a non-contact, automated visual inspection method used to check printed circuit board assembly. It uses high-resolution cameras and image-processing software to detect defects and inconsistencies in PCB production.

High-intensity light sources illuminate the PCB from various angles to enhance the visibility of components and solder joints. Then, high-resolution cameras capture detailed images of the PCB surface from various angles.

Specialized software aligns the captured images with a reference model of the PCB design. Deviations from the expected standards are then flagged as potential defects.

PCB Assemby Inspection Thorugh X-Ray

This is a non-destructive testing method that uses X-rays to visualize the internal structure of a PC board. It works by analyzing the difference in X-ray absorption rates of various materials within the PCB.

Different materials within the PCB absorb the X-rays at varying rates. Denser materials like solder and metal components absorb more, while less dense materials like fiberglass and plastic absorb less.

A detector on the other side of the PCB captures the X-rays that pass through. The resulting X-ray image reveals the internal structure of the PCB, including solder joints, component placement, traces, and potential defects like voids, shorts, or misalignment.

Functional Testing of PCBs Assembled

Functional testing, also known as FCT (Functional Circuit Test) verifies the overall functionality and performance of the completed PCB. It goes beyond testing individual components and focuses on how the entire board operates as a system in its intended environment.

A custom test process is designed to simulate an environment that closely mimics real-world operating conditions. It’s an indication of how well the circuit board will perform in its real environment. Changes can be made if the board performs poorly under functional testing.
