How Can Toki Automation Help in PCBA Manufacturing?

Toki Automation provides system integration and automation solutions in various aspect of PCBA and precision manufacturing such as:

• Laser and Traditional Tip Automated Soldering
• Precision Dispensing
• Inspection and Quality Checks
• BGA Rework

Laser and Traditional Tip Automated Soldering

Soldering is the primary method of attaching components to a PCB. Traditional soldering using a tip is usually done manually. With electronic devices become more complex, and smaller, circuit boards become increasingly tinier with many components. This creates many challenges in soldering especially in densely populated boards with micro components.

Toki Automation provides automated tip soldering using Hakko HF-600 technology. This helps make the soldering process more stable and repeatable. faster, and also reduces human errors and cost.

For high-density PCBs and heat-sensitive components, Toki also provides laser soldering. Laser soldering uses localised heat, giving better control over the area being soldered. Laser soldering minimizes the heat-affected zone (HAZ) and eliminating the risk of mechanical damage associated with physical contact.

We provide a comprehensive range of laser soldering configurations, that can be tailored to your specific production needs.

Types of Laser Soldering

• Toki 3-in-1 Precision Laser Soldering Platform: Wire, Paste & Preform
• Laser Solder Paste Soldering: Ideal for high-speed, precise placement on surface-mount components and micro-electronics.
• Laser Solder Wire Feeding: Perfect for automated point-to-point soldering, providing consistent volume and repeatable results.
• Laser Solder Preform Soldering: Ensures exact solder volume for critical joints in medical devices and aerospace applications.
• Laser Solder Ball Jetting (SBJ): The ultimate solution for high-speed, non-contact soldering of BGA and wafer-level packaging.

Precision Dispensing

Some electronic products need more than just components. They may also need materials like adhesives, sealants, or underfill during the manufacturing process.

The amount and position of these materials are important. If there is too much or too little, it can affect the quality of the product or cause problems later.

This is where precision dispensing can help. Toki Automation delivers advanced dispensing and coating solutions engineered for precise material control and repeatability. We specialize in high-mix manufacturing environments where consistent fluid application is critical to product reliability and yield. This helps make the process more consistent and reduces mistakes during production.

Inspection and Quality Checks

Making a product is only one part of the process. After the components are assembled, we also need to make sure everything is done correctly.

This is where inspection comes in. Toki provides high-speed Automated Optical Inspection (AOI) and Solder Paste Inspection (SPI) systems to detect defects at the source, ensuring 100% quality verification and drastically reducing downstream rework costs.

Toki also provides vision-guided robotics that combine AI-driven vision systems with robotic arms to enable precise 3D positioning, inspection-guided handling, and adaptive process control for complex, irregular assemblies. This can help make these tasks more consistent, especially when there are many products to check.

BGA Rework

What happens when a PCB has a problem? Does the whole board need to be replaced?

Not always. Sometimes, the PCB can be repaired through BGA rework.

Toki provides advanced BGA rework solutions engineered for high-reliability repair and precise thermal management. Our systems are designed for complex assemblies where accuracy, repeatability, and the protection of surrounding heat-sensitive components are critical to saving high-value PCBA. The process uses advanced thermal profiling which utilizing multi-zone infrared or hot-air heating, our systems create highly controlled thermal profiles to help reduce problems such as PCB warpage, delamination, and lifted pads.

This means automation is not only about making production faster. It can also help manufacturers improve consistency, quality, inspection, and yield recovery.

But there is another question. What happens when a manufacturer needs different machines and systems to work together?

That is where systems integration comes in.
