Why BGA soldering ball always crack(10)? Reduce the impact of PCB bending through the mechanism design change

Reducing the Impact of Stress on PCB Deformation through Mechanism Design In earlier sections, WorkingBear briefly mentioned the possible solution by  changing mechanism design to address the problem of solder cracking. One such approach involves replacing the SMDs (surface mount … Continue reading

Why BGA soldering ball always crack(9)? Increase the resistance of components to stress

How to increasing the ability of components to resist stress? (Continuing from the previous article) 2. No solder balls on BGA four corners, or use dummy balls instead of them. If you had studied the actual phenomenon of BGA solder … Continue reading

Why BGA soldering ball always crack(8)? Increase PCB stiffness to resist stress and avoid board bending

In the previous article, WorkingBear talked about how to improve the adhesion of PCA to resist the impact of stress. Today, We will move on to another topic: “How to increase the ability of components or circuit boards to resist … Continue reading

Increase solder paste volume will improve the MLCC capacitor broken?

Recently WorkingBear got complaint from R&D and ask increase the solder paste volume on the MLCC (Multi-Layer Ceramic Capacitor)  component pads to improve the capacitor broken issue. R&D said he had verified that the capacitor’s footprint in the board design … Continue reading

Copper Defined vs. Solder Mask Defined pad design for BGA soldering strength

Since the electronic product design moves from desktop to portable devices, the manufacturer also make electronic component as small as possible to meet this popular trend. Besides, the PCB thickness also become thinner and the associated soldering pads on the … Continue reading
