PCBA is a critical stage in the production of electronic devices, where components such as resistors, capacitors, and integrated circuits are mounted onto a printed circuit board (PCB) using soldering techniques. However, poor production can result in defects that compromise the quality and reliability of the final product. Let's take a look at some common technical terms of poor production in PCBA and how they can impact the functionality of electronic devices.

Solder bridging: This occurs when two or more adjacent solder joints are connected by a small amount of excess solder, creating a short circuit. Solder bridging can cause malfunctions in electronic devices and even damage them.

Tombstoning: This happens when a surface mount component partially lifts up from one end during the soldering process, resulting in an uneven or tilted placement. Tombstoning can lead to a weak or unstable connection and may cause intermittent failures.

Misalignment: This occurs when a component is not placed correctly on the PCB, causing it to be misaligned with other components. Misalignment can result in poor electrical contact and may affect the performance of the electronic device.

Insufficient solder: This happens when there is not enough solder applied to a component during the soldering process, resulting in a weak or incomplete connection. Insufficient solder can lead to intermittent failures or even complete failure of the device.

Solder voids: This occurs when small voids or air pockets are formed within the solder joint during the soldering process. Solder voids can weaken the connection and lead to premature failure of the component.

To ensure high-quality and reliable electronic devices, it is essential to address these technical terms of poor production in the PCBA process. By partnering with a reputable PCBA service provider that follows strict quality control measures and uses advanced manufacturing techniques, you can minimize the risk of defects and ensure the optimal performance of your electronic devices.

So, the next time we encounter an electronic device failure, keep in mind that poor production in the PCBA process may be a potential culprit. BQC will pass the quality inspection of at least four departments before shipment, and control the quality level by level.
