KKPCB offers Design for Manufacture and Assembly (DfMA) services. We conduct phased process design reviews, evolving from localized to comprehensive reviews. In production, we effectively identify manufacturing risks and process mismatches, allowing us to proactively address these issues.
By conducting 100% pad compatibility checks on order materials, we can identify solderability issues caused by incorrect material selection or unreasonable PCB pad design in advance. This prevents process defects due to material selection errors, avoiding production delays and ensuring timely delivery.
The final stage of the PCB assembly process is functional testing to verify that the PCB operates as expected. Additionally, depending on the application, other tests may be required. For example, automotive PCBs may undergo drop testing, while medical PCBs may require halogen testing.

Frequent Questions
What is PCB Assembly?
PCB Assembly is the process of mounting electronic components onto a printed circuit board to create a functional device. It includes component placement, soldering, inspection, testing, cleaning, and packaging. This process ensures that the components are correctly positioned, electrically connected, and the final PCB meets quality and performance standards.
What is PCB assembler?
How do you assemble a PCB?
Why is PCB Assembly service so important?
PCB Assembly service is essential because it ensures that electronic devices function correctly by accurately placing and soldering components onto the PCB. It provides quality control through inspection and testing, improves manufacturing efficiency, manages complex designs, and can be more cost-effective than in-house assembly. This service guarantees that PCBs are reliable, meet performance standards, and are produced efficiently, which is crucial for the timely and successful launch of electronic products.
Do you have any lower limit on PCB Assembly?
Yes, we typically have a lower limit on PCB Assembly orders to ensure cost-efficiency and operational feasibility. This minimum order quantity helps cover setup costs and ensures that the assembly process is economically viable. The specific lower limit can vary depending on factors such as the complexity of the PCB, component types, and production requirements. For precise information on minimum order quantities, it's best to discuss your project details with us directly.
What is your standard specification for PCB Assembly?
Our standard specification for PCB Assembly includes precise component placement within ±0.1 mm, high-quality soldering adhering to IPC-A-610 standards, and thorough inspection and testing, such as visual and functional checks. We ensure proper material handling, cleanliness of the PCB, and complete documentation, including assembly drawings and BOM. We use lead-free soldering in compliance with RoHS regulations and can handle both small-scale and large-scale production. These standards ensure that the assembled PCBs meet high performance, quality, and regulatory requirements.
Do you assemble boards fabricated by another board vendor?
How do you reduce the cost of printed circuit board assembly?
To reduce PCB assembly costs, focus on optimizing design to simplify the board and minimize component count, selecting cost-effective standard components, and improving layout efficiency. Utilize automation for precision and speed, increase production volumes for economies of scale, and implement lean manufacturing principles to reduce waste. Negotiate with suppliers for better terms, conduct thorough prototype testing to avoid costly revisions, and choose a cost-effective assembly service provider. These strategies collectively lower material, labor, and production costs while ensuring quality and efficiency.
What factors should l consider when choosing a PCB assembler?
What PCB assembly standards do you follow?
We follow several key PCB assembly standards to ensure quality and reliability, including IPC-A-610 for soldering and assembly workmanship, IPC-J-STD-001 for soldering practices, IPC-2221 for PCB design requirements, and ISO 9001 for quality management. Additionally, we adhere to RoHS compliance to limit hazardous materials, IPC-7711/7721 for rework and repair, and IPC-7351 for land pattern design. These standards collectively ensure high-quality assemblies and regulatory compliance.
How can l get a quick PCB Assembly Quote?

Can you provide partial turnkey PCB assembly?
Yes, we provide partial turnkey PCB assembly services, which means we can manage specific parts of the assembly process, such as component procurement, PCB fabrication, component placement, soldering, testing, inspection, and packaging, while allowing clients to handle other aspects. This flexible approach enables us to work collaboratively with clients to meet their specific needs and optimize the assembly process accordingly.
How much cost do you charge for a custom PCB assembly?
The cost of custom PCB assembly varies based on factors such as design complexity, component type and quantity, production volume, assembly process, testing and quality assurance requirements, and lead time. For an accurate quote, provide detailed project information, including design files and specifications, to receive a precise cost estimate tailored to your specific needs.
Do you have any specific requirements for BGA components?
Handling BGA (Ball Grid Array) components requires specific attention to ensure proper assembly and functionality. Key requirements include precise PCB design with adequate pad sizes, accurate soldering using techniques like reflow soldering, effective thermal management, advanced inspection methods such as X-ray to check solder joints, proper handling and storage to avoid damage, and accurate placement using automated machines. These practices are essential to ensure reliable connections, prevent overheating, and maintain overall component integrity.
What does your estimated price for printed circuit board assembly?
The estimated price for PCB assembly varies based on factors such as PCB complexity, component type and quantity, assembly volume, PCB size and thickness, and testing requirements. Larger production runs typically lower the per-unit cost, while specialized components, expedited services, and high testing standards can increase costs. For an accurate quote, detailed project information, including design files and production requirements, is necessary.
