Technical Tips for Successful BGA Rework

To ensure the reliability of your PCBA repair and prevent damage to sensitive components, our engineering team has summarized two critical factors for professional BGA soldering.

1. How to Set the Perfect BGA Rework Temperature Profile?
Setting an accurate temperature curve is the "soul" of BGA rework. A standard lead-free soldering profile typically consists of four stages:

Preheating Stage: Gradually increase the board temperature to 150°C to remove moisture and prevent PCB warping.

Soaking Stage: Maintain between 150°C - 180°C to activate the flux and balance the thermal difference across the board.

Reflow Stage: The peak temperature should be controlled between 230°C - 250°C (for Lead-free) to ensure full melting of solder balls.

Cooling Stage: Rapid but controlled cooling to form a fine-grained solder joint structure.

2. Selecting the Right BGA Nozzle
The suction nozzle (hot air nozzle) must match the size of your BGA chip to ensure uniform airflow and prevent "popcorn effects" on surrounding components.

Size Matching: The nozzle should be 2-5mm larger than the BGA chip.

Material Quality: Seamark ZM nozzles are made of high-grade titanium alloy, ensuring they never deform or rust under high temperatures.

Custom Solutions: We provide over 100 types of nozzles for BGA, CSP, QFN, and even customized shapes for specialized shield cans.
