High temperature resistant assembly circuit board:
PCBA, short for Printed Circuit Board Assembly, refers to the
process of mounting and soldering electronic components—such as
resistors, capacitors, chips, and connectors—onto a printed circuit
board (PCB). This assembly transforms a bare PCB into a functional
electronic unit, enabling devices like smartphones, computers, and
home appliances to operate efficiently. Essentially, it bridges
design and final product manufacturing in electronics.

Major PCBA Manufacturing Challenges:
| Challenge | Description |
| Miniaturization | Handling and placing extremely small (e.g., 01005) or complex
(e.g., BGA) components requires ultra-high precision and
specialized X-Ray Inspection (AXI). |
| Solder Quality | Controlling solder paste application and the reflow temperature
profile to prevent defects like bridging (shorts), tombstoning, and
weak joints. |
| Thermal Management | Preventing component overheating by effectively dissipating heat
from the densely packed components and managing thermal stress
during soldering. |
| Supply Chain | Dealing with component shortages, the risk of counterfeit parts,
and the constant need to manage component obsolescence (EOL). |
| DFM Issues | Ensuring the design adheres to manufacturing rules (e.g.,
sufficient clearance, proper test points) to avoid defects and low
yield loss. |
