EXPERT CIRCUIT BOARD SOLDER JOINT REPAIR SERVICES

Are you experiencing intermittent problems, malfunctions, or complete failure of your industrial circuit board due to solder joint issues? Solder joints are critical for connecting components to the board, and problems with these joints are a common cause of electronic failures. ROC Industrial offers expert solder joint repair services, restoring reliable connections and extending the life of your circuit board.

Understanding Solder Joint Problems

Solder joints are the electrical and mechanical connections between electronic components and the circuit board. Common solder joint problems include:

• Cold Solder Joints: These occur when the solder does not properly wet the component lead and the circuit board pad, resulting in a poor connection. They often appear dull and grainy.

• Cracked Solder Joints: These can be caused by thermal stress (repeated heating and cooling), vibration, or physical stress on the board. They can be very difficult to see without magnification.

• Solder Bridges: These occur when solder accidentally creates a connection between two points that should not be connected, causing a short circuit.

• Insufficient Solder: Not enough solder was used to create a strong connection.

• Excess Solder: Too much solder can also cause problems, such as solder bridges.

• Solder Voids: Air pockets or gaps within the solder joint, which weaken the connection.

Causes of Solder Joint Problems

• Poor Soldering Technique: Incorrect temperature, insufficient heating time, or improper use of flux during the original soldering process.

• Thermal Cycling: Repeated heating and cooling can cause solder joints to crack over time.

• Vibration: Constant vibration can weaken or break solder joints.

• Mechanical Stress: Bending or flexing the circuit board can stress solder joints.

• Component Lead Contamination: Oxidation or other contamination on component leads can prevent proper solder wetting.

• PCB Pad Contamination: Contamination on the circuit board pads can also prevent proper solder wetting.

Our Solder Joint Repair Process

1. Free Evaluation & Quote: Describe the problem and the circuit board type. Provide photos if possible. We provide a free quote.

2. Shipping: Ship the circuit board to our facility.

3. Diagnosis: Our technicians use microscopes and other inspection tools to carefully examine the solder joints and identify any problems. We look for cold joints, cracks, bridges, and other defects. We may also use electrical testing (multimeters, continuity testers) to check for intermittent connections.

4. Repair (Reflow/Resoldering): We use professional soldering and rework equipment to repair the faulty solder joints. This typically involves:Reflowing: Reheating the existing solder joint to improve its quality (if appropriate).
   Resoldering: Removing the old solder and applying fresh solder to create a new, reliable connection. We use appropriate flux and temperature profiles to ensure proper wetting and avoid damage to the components or board.

5. Cleaning: We clean the repaired area to remove any flux residue.

6. Testing & Quality Assurance: We thoroughly test the repaired board to ensure that the solder joint repairs have resolved the problem and that the board is functioning correctly.
