Expert in Comprehensive PCBA Full-Process Services
SMT chip mounting processing
I. We provide flexible, efficient, and comprehensive electronic manufacturing solutions that meet our customers’ end-to-end lifecycle needs—from R&D and pilot production to full-scale mass manufacturing.
Wide range of applications:Our services have been successfully deployed in high-reliability industries such as telecommunications equipment, medical devices, computers and servers, industrial control systems, automotive electronics, and smart home appliances.
II. Advanced Hardware Equipment:
We are equipped with industry-leading, fully automated production lines to ensure machining accuracy and production efficiency:
Mounting equipment:Equipped with a high-end, fully automatic, multi-functional SMT placement machine imported from overseas, it can stably mount components ranging from ultra-small resistors and capacitors such as 0201 and 0402 to QFPs with a pin pitch of only 0.3 mm, as well as precision integrated circuit chips like BGAs and QFNs with a ball pitch of 0.5 mm or less.
Welding equipment:Equipped with an imported 12-zone nitrogen reflow soldering oven, it enables precise control of the soldering temperature profile, thereby ensuring high yield for all types of components, particularly BGAs.
Supporting processes: Equipped with fully automatic solder paste printers, selective wave soldering machines, automatic coating systems, and milling-type automatic board separation machines, among others, to meet the complete processing requirements of complex PCBA assemblies.
SPI (Solder Paste Inspection System):Perform real-time inspection of solder paste thickness, area, and volume immediately after printing to prevent soldering defects at the source.
AOI (Automated Optical Inspection):After reflow soldering, a high-resolution camera is used to automatically inspect component placement position, polarity, and solder joint quality (including short circuits, insufficient solder, and misalignment).
X-ray inspection:For BGA, QFN, and other packages with bottom-visibility-restricted solder joints, X-ray inspection is a critical method for detecting internal defects such as bridging, voids, and bubbles, thereby ensuring the reliability of high-density printed circuit boards.
MES System:Achieve end-to-end traceability of the entire product manufacturing process.
Fully automatic laser marking machine: capable of engraving 2.5 mm × 2.5 mm QR codes, ensuring reliable product traceability.
ESD Online Monitoring System:Ensure the reliability of the production environment.
III. A Comprehensive Testing System:Quality stems from process control. We have established a four-tier inspection defense system, spanning from raw materials to finished products:
Incoming Quality Control (IQC):Verify and inspect all materials provided to customers (or purchased on their behalf) to ensure that the material models and specifications match the BOM, thereby preventing errors at the source.
First Article Inspection:During changeovers or at scheduled intervals, each production line must conduct a full inspection using the first-article inspection device to verify process and material accuracy.
Real-time monitoring:Continuously monitor and record key process parameters, including solder paste printing settings, pick-and-place machine drop rate, and reflow oven temperature profiles, to ensure process stability—2.
Final Quality Assurance (FQA):All products undergo final quality inspection in accordance with IPC-A-610 (Level 2 or higher) standards, as well as the requisite functional testing, prior to shipment, ensuring that only fully qualified products are delivered to customers.
We adhere to and optimize internationally recognized SMT process flows to ensure that every circuit board undergoes highly consistent, precision processing.
Our goal is to deliver “zero-defect” products, and to achieve this, we have established a comprehensive quality-control network that spans the entire production process:
