PCB Assembly
PCB assembly, also known as PCBA or PCB'A, refers to the process of mounting electronic components onto a Printed Circuit Board (PCB) through Surface Mount Technology (SMT) or Through-Hole Insertion (DIP) processes.
PCB and PCBA
PCB, standing for Printed Circuit Board, is a fundamental electronic component that does not include any electronic parts by itself. Manufactured using electronic printing techniques, PCBs are indispensable in the electronics industry. In contrast, PCBA denotes the finished state of a PCB after all assembly processes have been completed, representing a more comprehensive manufacturing workflow.
SMT and DIP
SMT technology allows for the direct mounting of miniature electronic components onto a PCB without the need for drilling holes. This process includes PCB positioning, solder paste printing, component mounting, reflow soldering, and quality inspection. Conversely, DIP technology is suitable for larger components that require drilling holes on the PCB and inserting component leads into these holes, followed by subsequent processes such as wave soldering.
PCBA Manufacturing Process
The manufacturing process of PCBA encompasses a series of steps from electronic component procurement, PCB prototyping, SMT and DIP processes, to circuit assembly testing, and final product assembly.
PCB Assembly Manufacturing Services
Yongchangtai offers comprehensive PCB assembly manufacturing services, including full assembly and partial assembly options. In the full assembly service, we are responsible for the entire production process, including material procurement, order tracking, quality inspection, and final assembly. For partial assembly services, customers can order PCBs and some materials themselves, and we will complete the remaining production tasks.
How to Obtain One-Stop Consulting Services for PCB Assembly Manufacturing
Customers can obtain Yongchangtai's BOM quotation service by submitting their BOM and the quantity to be produced. We will provide a quotation within 24 hours. The BOM should include information such as quantity, part number, manufacturer's name, and model number.
PCBA Testing Process
Before the delivery of PCB components, we will conduct a series of tests, including visual inspection, X-ray testing, automatic optical inspection, in-circuit testing, and functional testing, to ensure the quality of the components.
Professional Procurement and Cost Optimization
Our procurement team focuses on obtaining components from the same supplier, optimizing packaging and quantity selection to reduce costs. We have the capability to handle hard-to-order materials and obsolete components, ensuring timely material supply and design integrity.
Importance of On-Time Delivery and DFM
We understand the importance of on-time delivery and synchronize material procurement during the PCB manufacturing process. DFM is crucial for batch soldering, and we will review the customer's Gerber files, BOM, assembly documents, and circuit diagrams to prevent any engineering issues.
Testing and Quality Assurance
Our services include comprehensive electrical testing and X-ray testing to ensure soldering quality. We provide professional guidance on how to distinguish test points and troubleshooting support to meet the customer's testing requirements.
Cost-Effectiveness and Partnership
We compare material prices among large suppliers through our solid cooperation relationship, selecting materials with good quality and low prices, thereby reducing material costs.
