Our BGA Assembly Process
The process of BGA assembly requires precision, attention to detail, and state-of-the-art technology. Below is the step-by-step BGA assembly process that we employ:
1
PCB Fabrication and Preparation
Initially, we fabricate the PCB based on your design specifications, ensuring that all layers and signal routes are in place to support the BGA components. We also prepare the PCB for the assembly process by cleaning and conditioning the surface.
2
Solder Paste Printing
We begin the process by printing a precise layer of solder paste onto the PCB’s surface using an advanced screen-printing process. The solder paste will provide the necessary connection medium for BGA components.
3
High-Precision BGA Component Placement
Using high-speed automated placement machines, we accurately position each BGA component on the PCB. The placement process is crucial to ensure that every pin of the BGA is aligned with the solder paste, ready for reflow soldering.
4
Reflow Soldering
Once the components are placed, the PCB is passed through a reflow oven, where it is heated to the optimal temperature to melt the solder paste, creating strong and reliable connections between the BGA component and the PCB.
5
X-Ray Inspection of Solder Joints
After reflow soldering, we use X-ray inspection to check the solder joints beneath the BGA components. This step ensures that there are no hidden defects, such as cold solder joints or voids.
6
AOI Inspection
We then perform Automated Optical Inspection (AOI) to ensure that the BGA components are correctly positioned and soldered. This inspection identifies any potential surface defects or misalignments.
7
Functional Testing
After visual inspections, we conduct functional testing to verify the electrical performance of the BGA assembly. This ensures that the assembly meets all operational specifications and is free from defects.
8
Final Quality Inspection
Before shipping, we conduct a final quality inspection to ensure that the assembly is fully operational, mechanically sound, and meets our stringent quality standards.
