Through Hole PCB Assembly Services
Through Hole Component Placement
We offer both manual as well as auto insertion of through hole (TH) components. While with axial lead components, the leads are placed on both sides of the components, radial components have the leads on one side of the components.
Automated Through Hole PCB Assembly
We use automated through hole assembly method to effectively place radial and axial components. Not only does it lead to reduced errors and improved delivery times, with reduced material handling and labor costs, it is extremely cost effective too.
Manual Through Hole PCB Assembly
This technique is used for low-volume runs as also for custom parts and sub-assemblies attached to the board. Manual assembly is also used in the cleanup of the automated assembly process. These are in instances where components aren’t easily inspected by the automated inspection equipment and a technician is required to verify placement and do any touch ups.
Manual Solder
Manual hand soldering stations are used to assemble through hole parts into boards. This is typically used for low volume assemblies, as also prototypes. Manual Solder in through hole PCB assembly takes longer time than usual.
Selective Solder
It helps solder individual through-hole components on a PCB using a solder fountain. Compared to manual soldering, it is faster, repeatable and leads to reliable results.
Wave Solder
Apart from being much faster than manual soldering, wave soldering also produces joints with a much higher degree of reliability, and this makes it ideal for large scale through hole PCB assembly.
PCB Conformal Coating
In through hole PCB assembly, we offer a range of conformal coating options to protect the electronic components against various types of environmental hazards, debris, and aggressive chemicals. Some of these include Acrylic Resin, Parylene, Polyurethane, Epoxy, Silicone and more.
PCB Encapsulation
We offer substantial protection against physical shock and chemical exposure through our PCB Encapsulation services. This is ideal for environments that have prolonged stress and goes a long way in ensuring optimum performance of the electronics.

Through hole PCB assembly process
The broad steps involved in the manual and automated through-hole assembly include:
- Preparing the bare board.
- Manual or automated insertion of components. High speed installation requiresspecialized equipment that can place components axially or radially, as per the design requirements.
- Using reflow oven to fix soldering paste appropriately.
- Manual or automated wave soldering to precisely solder through-hole components.
- The use of advanced aqueous washing systems to remove any contaminants from the circuit boards.
- Detailed inspection using different inspection tools and techniques, such as automated optical inspection, X-ray inspection and more.
- Conformal coating as well as device programming, where needed.
- Shipping and Delivery of final through hole PCB assembly.

Through Hole PCB Assembly Testing Capabilities
- In-Circuit Testing：Widely in use for high volume production lines, they help check the soldering and components.
- Automated Optical Inspection：With this inspection, you can rest assured that there are no soldering or component defects.
- Automated X-Ray Inspection (AXI)：Known to improve the quality of through-hole circuit, it inspects for short circuits, fills and more.
- Burn-in Tests：These tests are crucial in that they test the reliability of the PCB in the real time environment.
- Assisted Visual Inspection：Visual inspection by experts helps check accuracy of soldering as well as placement of components.
The above robust testing methodologies will ensure that you receive error free PCBs and that you do not need to deal with costly errors at a later stage when your product has hit the market.

Frequent Questions
What is Through Hole PCB Assembly?
Through-hole PCB assembly involves inserting electronic components into pre-drilled holes in a PCB and soldering them on the opposite side, creating strong electrical and mechanical connections. This method is valued for its durability and is commonly used in applications requiring robust connections, such as automotive, aerospace, and military electronics. While it provides strong mechanical support, it requires more space on the PCB and limits component density compared to surface-mount technology (SMT).
What are the advantages of through hole assembly?
For one, it offers reliability on account of the stronger bonds between the components and the board. It is also preferred for large components and in applications that undergo environmental stress. Their durability also makes them a good choice for prototyping.
