During the operation of mining machines, improper use or environmental factors can sometimes lead to severe damage, making the equipment unrepairable or the cost of repair too high. According to our after-sales terms, the following examples, though not exhaustive, fall into the category of irreparable damage, and repairs will not be provided by the official service team. Below, we illustrate common cases of such damage to help users understand these issues and their possible causes.
I. Burnt Circuit Board
Case Description:
The equipment experiences a short circuit or overcurrent, causing severe burning of components and traces on the circuit board, often accompanied by scorch marks or a burnt smell.
Reason for Non-Repairability:
Severe burning damages the multi-layer structure of the circuit board, making it difficult to ensure electrical performance and equipment safety even after repair.
II. Corrosion/Oxidation
Case Description:
Mining machines are exposed to humid or high-salt environments (e.g., coastal areas) over extended periods, leading to corrosion on the circuit board surface and components. This results in rust or oxidation layers, with some solder joints and contact points failing.
Reason for Non-Repairability:
Corrosion or oxidation causes widespread irreversible damage to the circuitry, and restoration would not reliably restore the circuit board's integrity.
III. PCB Breakage
Case Description:
The circuit board suffers from significant external force or bending, resulting in physical breakage or delamination that severely impacts circuit integrity.
Reason for Non-Repairability:
A broken PCB destroys the continuity of internal circuits. The cost and complexity of repair are high, with a low success rate. In such cases, the entire board typically needs replacement.
These examples serve as a reference to help users recognize signs of severe damage that fall outside the scope of repair. For any questions regarding the warranty terms or repairability of specific cases, please contact our after-sales support team.
