　　FPC Plating Process

　　1. Pre-treatment for FPC Electroplating

　　After the flexible printed circuit (FPC) undergoes the coating process, the exposed copper conductors may be contaminated by adhesives or ink. Additionally, oxidation and discoloration caused by high-temperature processes can occur. To ensure good adhesion of the plating, these contaminants and oxidation layers must be removed, leaving the conductor surface clean.

　　However, some contaminants are strongly bonded to the copper conductor, making it difficult to remove them with weak cleaning agents. Strong alkaline abrasives and brushing are typically used for this treatment. Since the adhesive used in the cover layer is often epoxy-based, which is not resistant to alkaline agents, this can weaken bonding strength. Although not immediately apparent, during the electroplating process, the plating solution may seep into the edges of the cover layer, and in severe cases, cause delamination of the cover layer.

　　At the final soldering stage, solder might seep beneath the cover layer. Therefore, the pre-treatment cleaning process has a significant impact on the basic characteristics of the FPC, making it essential to pay close attention to the processing conditions.

　　2. Thickness of FPC Electroplating

　　The deposition rate of electroplating metal is directly related to the intensity of the electric field, which varies depending on the shape of the circuit and the position of the electrodes. Generally, the thinner the conductor line and the sharper the terminal end, the stronger the electric field, leading to a thicker plating in those areas.

　　In FPC applications, there are often wide differences in the width of conductor lines within the same circuit, resulting in uneven plating thickness. To prevent this, auxiliary cathode patterns are added around the circuit to absorb uneven current distribution across the plating pattern, ensuring uniform plating thickness across all areas.

　　Electrode structure is key here. A compromise approach can be adopted, where stricter standards apply to areas requiring high plating uniformity, such as molten solder (lead-tin) and gold plating for metal wire bonding, while areas requiring plating for general corrosion protection may have more relaxed thickness requirements.

　　FPC manufacturer

　　3. Contamination of FPC Electroplating

　　Immediately after electroplating, the plated surface may appear fine, but stains, dirt, or discoloration can appear over time. Often, these issues are not detected during factory inspections but are discovered during customer acceptance tests. This happens when the plated surface is not adequately rinsed, leaving residual plating solution, which reacts chemically over time, especially on the flexible surface due to its softness and uneven texture.

　　To prevent this, thorough rinsing and drying are essential. A high-temperature thermal aging test can verify whether rinsing was sufficient.

　　FPC Chemical Plating

　　When the conductor to be plated is isolated and cannot serve as an electrode, chemical plating must be used. Chemical plating solutions are highly reactive, and a common example is chemical gold plating. The chemical gold plating solution is an alkaline solution with a very high pH value.

　　When using this process, it is easy for the plating solution to seep beneath the cover layer, especially if the lamination quality control is poor, leading to weak adhesion. Displacement reactions in chemical plating exacerbate this problem, making it difficult to achieve ideal plating conditions.

　　FPC Hot Air Leveling (HASL)

　　Hot air leveling was originally developed for rigid printed circuit boards (PCBs) to coat them with lead-tin. However, this technique has been applied to FPCs due to its simplicity. Hot air leveling involves immersing the board vertically into molten lead-tin and blowing off excess solder with hot air.

　　These conditions are quite harsh for FPCs. Without special measures, FPCs cannot be immersed in molten solder. To address this, FPCs must be clamped between titanium-steel meshes before immersion. Additionally, the surface of the FPC must be cleaned and coated with flux beforehand.

　　Due to the harsh nature of the hot air leveling process, solder may seep beneath the edges of the cover layer, especially if the bonding strength between the cover layer and the copper foil is weak. Since polyimide films are prone to moisture absorption, moisture can evaporate suddenly under the heat, causing blistering or even delamination of the cover layer. Therefore, drying and moisture control must be performed before FPC hot air leveling.

　　Have you ever been awakened by the embarrassing moment that Amy’s watch on your wrist suddenly slipped in the morning? Yes, you are not mistaken, that is, the Amy watch that appears so elegant and accurate in your daily life will actually “slip silk”! This is not just an accident, but more like a silent humorous drama, which makes people laugh and cry. So, in the face of such a situation, what should we do? Don’t worry, follow me to explore the solution!According to professional reports, 126500 There will be a great period of growth, and the market business is constantly expanding, and it will definitely become bigger and bigger in the future. https://finewatchcare.com/products/fwc-for-rolex-126500ln-0001-watch-protection-film?_pos=4&_sid=1408dd4d0&_ss=r&variant=46788400677151

　　First of all, understand the truth of “silky”

　　The word “silky thread” sounds a bit abstract, but actually refers to the relative sliding between the strap and the clasp. This usually happens when the strap material is soft, the clasp design is not tight enough, or the strap is worn for a long time. Imagine, it’s like wearing a soft scarf and being blown away by a breeze inadvertently.

　　Diagnostic steps: self-check and help

　　Once the phenomenon of “wire slipping” is found, the first step is self-diagnosis-check whether the strap has worn to a certain extent, whether the clasp is loose or whether there is any foreign body stuck. If the problem lies with yourself (for example, too much sweat makes the wrist strap greasy), you may need to adjust your wearing habits or choose a watch with a more sweat-proof material.

　　If self-diagnosis can’t solve the problem, you might as well seek professional help. It is a good choice to go to the local watch repair shop for inspection and maintenance. Remember to bring your Amy watch and any accessories that may affect the problem (such as a spare strap), so that you can find the problem more accurately.

　　Maintenance suggestion: DIY and professional service

　　You can try to solve the slight “silky” problem yourself. For example, use some small tools (such as a small screwdriver or a special clock tool) to adjust the tightness of the watch buckle. Of course, before any operation, please make sure to understand the basic operation steps and safety knowledge.

　　For more complicated situations, it is recommended to seek professional maintenance services. Professional watchmakers will use special equipment and tools to conduct a comprehensive inspection and repair of your Amy watch. They can not only accurately judge the problem, but also have experience in repairing all kinds of complex mechanical failures.

　　Preventive measures: daily maintenance and selection

　　In addition to solving the problems, daily maintenance is also the key to prevent the phenomenon of “silk slipping”. Cleaning the watch regularly, avoiding long-term contact with water or chemicals, and choosing a watch style that suits your wrist size and activity habits are all part of the preventive measures.

　　Generally speaking, although “Amy Watch Slipping Wire” has brought embarrassment and inconvenience to some extent, through correct diagnosis, appropriate solutions and daily maintenance measures, we can effectively deal with this situation and keep our watch in the best condition.

　　So, the next time you encounter such an episode, please keep a calm and optimistic attitude-after all, in this world full of small surprises, the “silky” Amy watch is also a unique memory!

For these reasons, I think dandadan The situation is still optimistic, and the market is still in a blue ocean stage. https://dandadan.top/
