Printed circuit board assembly is a process that requires not only knowledge of printed circuit board components and assembly, but also understanding of printed circuit board design, printed circuit board manufacturing, and a deep understanding of the final product. Circuit board assembly is just one of the challenges in delivering a perfect product for the first time.

Printed circuit boards (PCBs) are widely used in many industrial and consumer electronics products. The multifunctionality of PCB comes from its lightweight, compact, and flexible structure, which can adapt to any complex circuit. Although PCBs are relatively common, their complexity makes it crucial to procure new circuit boards from reliable suppliers. Printed circuit board assembly services take advantage of these complexities.

Hitech Group provides comprehensive printed circuit board assembly services to help our customers fully realize their designs. We have extensive experience in collaborating with clients in highly innovative industries such as communication, automotive, industrial control, medical equipment, oil and gas, and security.

PCB manufacturing
Hitech Group provides complete PCBA manufacturing and partial PCB assembly manufacturing. In the comprehensive PCB assembly manufacturing, we handle PCB production, material procurement, online order tracking, incoming material certification/quality inspection, and final assembly. In some PCB manufacturing, you can order PCBs and some materials yourself, and we complete other parts.

How to obtain one-stop consultation for PCBA manufacturing?
BOM quotation, please send your BOM to Hitech Group and inform us of the quantity of PCBs to be manufactured. We will provide you with a PCBA quotation within 24 hours. The bill of materials must include quantity, tag number, manufacturer name, and manufacturer model.
Before delivering the PCB components, we will conduct various tests on them.
Visual inspection: General quality inspection

X-ray inspection: Check for short circuit cold soldering or bubble issues in BGA, QFN, and other soldering.
Automatic optical inspection: Check for virtual soldering, short circuits, missing parts, polarity reversal, etc.
Online testing
Functional testing (based on the testing steps you provided)
What is the definition of PCBA?
PCB refers to a blank board, while PCBA is a complete PCB component that contains all the electronic components required to make the board operate as required. PCBA can also refer to the process of assembling a circuit board with necessary components.
PCBA companies can use two main methods for PCB assembly:

Surface mount technology
Surface Mount Technology (SMT) is an assembly process that involves mounting electronic components onto the surface of a PCB. It has high automation and flexibility, and allows for higher connection density. It enables manufacturers to incorporate complex circuits into small components.
The four basic steps of PCBA SMT are:
Prepare PCB: First, the assembly personnel place the solder paste on the board where it is needed.
Placement of components: Next, assembly personnel typically use picking and placing machines to place the components on the board.
Reflow soldering: Assembly personnel then heat the circuit board in a reflow oven until the solder paste reaches the temperature required to form solder joints.
Inspection: Assembly personnel conduct inspections throughout the SMT process, including before connecting components and before and after reflow soldering.
Through-Hole technology
Through-hole technology is an assembly process that involves drilling holes in a PCB through which electronic components called leads can be connected. It is a technology that is older than SMT, but establishes stronger connections between circuit boards and components, making assembly more durable and reliable.
The through-hole assembly can be fully automatic or semi-automatic. The steps of PCBA through-hole process include:
Drilling: The first step in the through-hole process is to drill holes on the circuit board. The size of these holes must be suitable for the component leads.
Place the lead: Next, the assembly worker places the lead in the hole.
Welding: The next step in this process is welding. This step ensures that the components are firmly fixed in place.
Inspection: Throughout the process, inspect the components to ensure that the PCBA operates as expected.
