Are you able to source components for my project?

Yes, we’ve built strong, trusted relationships with component suppliers over the years, giving us access to stock with fast turnaround times that fit your project deadlines. This ensures there are no delays in the supply chain, while providing full traceability and the reliability you can trust.

Do you offer conformal coating?

Yes, ABL Circuits offers conformal coating for your PCBs.This protective layer shields boards from moisture, dust, chemicals, and temperature extremes, helping to improve reliability and extend the lifespan of your electronics.

Do you offer Surface Mount Technology (SMT) and Through-Hole Technology (THT)?

Yes, ABL Circuits offers both Surface Mount Technology (SMT) and Through-Hole Technology (THT) for PCB assembly. SMT allows for compact, high-density boards and fast production by mounting components directly onto the PCB, while THT provides superior durability by inserting components into drilled holes and soldering them on both sides. Whether your project prioritises speed, strength, or both, our assembly processes ensure high-quality, reliable, and long-lasting PCBs.

What are the benefits of having ABL Circuits manage my entire PCB project?

Having ABL Circuits manage your entire PCB project means one partner takes care of everything from design and component sourcing to assembly and final delivery.With ABL Circuits, everything is handled end-to-end, reducing emails, avoiding delays, and removing the headaches of coordinating multiple suppliers. Sometimes, one experienced partner who oversees the whole process is worth a dozen who don’t communicate.

What is PCB Assembly?

PCB assembly is the crucial stage that follows the design and manufacturing of a custom printed circuit board. Once the initial design is finalised and the blank PCB is produced, the next step is sourcing and mounting all necessary integrated circuits (ICs) and components, this is the assembly process.

At this point, the PCB’s substrate and etched traces are in place, but the board itself remains non-functional until all required components are precisely soldered into position. Careful and accurate assembly ensures the PCB performs as intended, bringing your design to life.

Component Sourcing for PCB Assembly

At ABL Circuits, we take pride in managing the entire component sourcing process for our clients. Whether it’s for a prototype PCB assembly or a full production run, our expert team ensures optimal component selection based on performance, cost, and availability. With over 40 years of experience in the industry, we leverage our extensive supplier network to secure the best components at competitive prices.

Thanks to our strong relationships in the electronics supply chain, we can guarantee timely access to high-quality components that meet your exact specifications. Our procurement expertise ensures your project runs smoothly from start to finish, with no compromise on quality.

While many clients trust us to handle component sourcing, we’re also happy to assemble PCBs using client-supplied components when needed, particularly when working with proprietary parts or branded devices. In such cases, we’re accustomed to operating under strict NDAs to protect your intellectual property.

Skills and Techniques in PCB Assembly

Once components are sourced, the next step is mounting them onto the PCB. This is done using one of two primary methods: Surface Mount Technology (SMT) or Through-Hole Technology (THT). Each approach has its advantages, depending on the project's requirements.

Regardless of the method, PCB assembly demands precision and expertise. Soldering—whether performed manually or through automated machinery, is a critical process that ensures components are securely and accurately affixed to the board.

Achieving a reliable, high-performance PCB requires:

Technical craftsmanship to handle intricate components
Experience in working with various assembly techniques
High-quality tools and materials for precision and durability
Attention to detail to ensure every connection is flawless

Mastering these skills is essential to delivering a PCB that performs optimally in its intended application.

Key Differences Between SMT and THT Assembly

PCB assembly uses two main techniques:

Surface Mount Technology (SMT)

SMT components are soldered directly onto the board’s surface, offering:

Faster, automated assembly
Often using Pick and Place machines.

Smaller, cost-effective components
Ideal for compact, high-density designs.

Pre Build CheckFaster, automated assembly
Connections may be weaker under stress.

Through-Hole Technology (THT)

THT involves inserting component leads through drilled holes for a stronger connection:

More durable and reliable
Ideal for high-vibration or high-power applications.

Longer production times
Additional drilling and soldering steps required.

Larger, pricier components
Due to lead-based design and extra material.
