Through Hole PCB Assembly

Get end-to-end through hole PCB assembly (THA) from prototypes to production. At Technotronix, we are committed to delivery of high-end technology solutions. To this end, we offer a complete range of through hole PCB assembly capabilities resulting in PCBs that are in compliance with international quality standards.

Our through hole PCB Assembly services comprise of both manual and automated techniques. While our manual techniques can handle complex assemblies, the automated ones are best suited for small-volume production as also reduced material handling. We provide through hole PCB assembly at the highest quality level and in a cost-effective manner.

Capabilities of Through Hole PCB Assembly

We are fully equipped to handle the following through-hole PCB assembly services:

  • Manual and automated placement of components
  • Double Wave Flow Solder
  • RoHS soldering using tin-lead solder
  • Functional testing

Above everything, we have a highly trained and experienced team that specializes both in hand soldering of components as also automated insertion for both axial and radial components as also automated dual wave solder.

In addition to through hole PCB assembly, we also provide value-added services, such as conformal coating, labelling, surface finishing and complete PCB encapsulation.


Thermal Profiling

Thermal Profiling

This is used to discover the temperature profile that works best for the through hole PCB and to point out defects such as Insufficient solder, misaligned components, marginal joints and more.

Flying Probe Testing

Flying Probe Testing

This is particularly used in cases of low volume and highly complex assemblies and helps in detecting missing components as also to validate the component placement.

ICT Testing

ICT Testing

ICT (In-Circuit Testing) is used extensively for high volume through hole PCB assembly production; it is extremely efficient in detecting parametric failures, PCB layout-related faults, and component failures.

Functional Testing

Functional Testing

Used to authenticate board operations and behavior, Functional Testing helps us detect faulty component values, functional and parametric failures.

All of the above enable us to ensure reliability in our PCB Assembly process with reduced production losses, employee safety, process stability, extended equipment life, reduction in environmental issues and optimum usage of spare parts inventories.

Benefits of Through Hole PCB Assembly

The range of through hole PCB assembly comes with a varied benefits including:

  • Withstanding stress: As opposed to SMT components, through-hole components are known for their ability to withstand mechanical and environmental stress.
  • Perfect for large components Through-hole works well for large components that have to undergo high power and high voltage
  • High heat tolerance Known for their high heat tolerance, they find application in a number of industries, particularly military and aerospace.
  • Ease of Prototyping Through-hole PCBs also lend themselves to ease of prototyping and improved reliability
  • High Reliability Through-hole PCBs are best used for high-reliability products that require stronger connections between layers.

Little surprise then, that even though surface mount components allow for denser configurations, for larger and heavier components that require strong bonds, through-hole technology has remained resilient and relevant.

In the Through hole PCB assembly, the leads of the components are inserted into the holes which are drilled in bare boards and soldered to pads on the opposite side either by automated assembly insertion or manual assembly.

The through hole PCB mounting components called as axial and radial leads components.

There are multitude of applications of the through hole PCB assembly; hence they are widely used in power electronics and other devices which generate a lot of heat.

THT PCBA is abbreviated for Through Hole Technology Printed Circuit Board Assembly.

Well, whether to choose Through hole PCB assembly Or SMT PCB Assembly is totally depends on your requirement of project. Most of the integrated circuits go for the SMT package. However, for connectors, switches, or mechanical power parts, the standard way is to use through-hole parts

Yes, we inspect the boards using X-ray and therefore offer total reliability.
