Question 1

What is printed circuit board assembly?

Accepted Answer

Printed circuit board assembly (PCBA) is the process of placing and soldering components onto a bare PCB to create a functional electronic circuit. It involves surface mount technology (SMT) and thru-hole technology, forming the backbone of electronic devices used in the medical, telecommunications, and aerospace industries.

Question 2

What are the steps of PCB assembly?

Accepted Answer

The PCB assembly process typically includes design file review, component placement (SMT or thru-hole), soldering (wave or reflow), inspection (AOI or functional testing), and final assembly. Additional steps like conformal coating or potting may be included to protect the board from environmental stressors.

Question 3

How much does PCB assembly cost?

Accepted Answer

PCB assembly costs vary based on factors like the complexity of the design, type of components, production volume, and additional services such as testing or coating. A prototype run may cost more per unit, while large-scale production typically benefits from a larger scale.

Question 4

How long does PCB assembly take?

Accepted Answer

The timeline for PCB assembly depends on the complexity of the design, availability of components, and production volume. Prototypes can take a few days to a couple of weeks, while large-scale production may take several weeks to complete.

Question 5

What industries rely on PCB assembly?

Accepted Answer

PCB assemblies are crucial in a wide range of industries, including medical devices, military electronics, aerospace, telecommunications, consumer electronics, and industrial equipment. Each sector requires unique PCB designs to meet performance and regulatory standards.

Question 6

What is the difference between SMT and thru-hole assembly?

Accepted Answer

Surface mount technology (SMT) places components directly onto the surface of the PCB, offering compact, high-density assemblies. Thru-hole assembly, by contrast, involves inserting components through holes in the board, providing stronger mechanical bonds and higher durability for rugged applications.

Question 7

Do you have both lead and lead-free solder capability?

Accepted Answer

Yes, we offer both lead and lead-free solder options to meet diverse regulatory and product needs. Our tightly controlled manufacturing processes prevent cross-contamination, maintaining the integrity of each type of solder throughout production.

Question 8

What percentage of products do you test?

Accepted Answer

We perform 100% testing on every product we assemble to achieve the highest level of quality and customer satisfaction. Our testing methods include automated optical inspection (AOI), functional testing, and in-circuit testing to validate performance and reliability.

Question 9

Does your AOI have the capability to inspect thru-hole components?

Accepted Answer

Yes, our advanced AOI systems inspect both surface-mount and thru-hole components in a detailed 3D format. This technology allows us to accurately assess complex, odd-form components that are difficult to inspect manually.

Question 10

What type of conformal coating material do you use?

Accepted Answer

We apply an acrylic-based coating called Humiseal 1B73, which offers strong protection against moisture, dust, and environmental hazards. Acrylic coatings are valued for their fast drying time, flexibility, and easy reworkability, making them an excellent choice for a wide range of electronics.

Question 11

What documentation is needed to quote my complete PCB assembly?

Accepted Answer

To provide an accurate quote, we need your PCB files, mechanical drawings, and an upper-level bill of materials. These documents allow us to assess component requirements and project complexity, helping us create a detailed and competitive estimate.

Question 12

Are you able to source all of the materials for PCB assembly?

Accepted Answer

Yes, we can source all the materials required for your assembly. Our extensive supply network enables us to secure the necessary components, reducing lead times and ensuring your project stays on schedule.
