In the realm of industrial safety, the eyewash station stands as a sentinel, ready to spring into action at a moment¨s notice. The water within this lifeline must be of the highest quality, meeting the standards of potable tap water, in alignment with national drinking water regulations. However, the eyewash station is not a daily fixture in our routines; it is an emergency response tool, deployed only when a chemical splash occurs, endangering the eyes, face, or other parts of the body. Due to its infrequent use, the water within can become stagnant, prompting a critical question: how can manufacturers ensure the water remains pristine and safe?understand First Aid Eye Wash Units In order to better serve customers and reflect the core competitiveness of products. https://www.bohuasafety.com/

　　

　　The answer lies in a meticulous approach to water maintenance, born from years of experience in eyewash station production. The water within an eyewash station should be refreshed on a weekly basis to prevent any degradation in quality. But how does one implement such a regimen?

　　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.

　　2. Key Steps in the Manufacturing Process

　　

　　Material Selection and Layer Construction

　　

　　The manufacturing of multilayer flexible printed circuit boards begins with selecting the appropriate materials. Polyimide is the standard base material due to its high-temperature resistance and flexibility. Copper layers are added to create conductive pathways, and the number of layers depends on the complexity of the design.

　　

　　Each layer is carefully constructed, starting with the outer flexible layer, followed by insulating and conductive layers in a sequence. The layers are aligned meticulously to ensure connectivity across all components.

　　

　　Imaging and Etching Process

　　

　　Once the layers are in place, the next step is to image and etch the copper to define the circuit paths. Photolithography techniques are used to project circuit designs onto the copper layer, which is then etched to remove unwanted areas. This step is critical to creating precise electrical pathways.

　　

　　Layer Alignment and Lamination

　　

　　After each layer is imaged and etched, the different layers are stacked and aligned using precision machinery. Any misalignment can cause failure in the final product, especially as the complexity of the multilayer flexible printed circuit board increases. The layers are then laminated using heat and pressure to form a single, unified structure.

　　

　　Drilling and Plating

　　

　　Once laminated, the board is drilled to create vias (small holes) that connect the different layers electrically. These vias are plated with copper to ensure proper conductivity between layers. The drilling and plating processes must be executed with high precision, as any defects can lead to failures in the finished product.

　　

　　Testing and Quality Control

　　

　　The final steps in the multilayer FPC manufacturing process involve rigorous testing to ensure electrical performance and durability. Automated optical inspection (AOI) systems are often used to detect defects, while electrical testing verifies the connectivity of all circuits. The quality control process ensures that the FPCs meet the high standards required for industries such as automotive, aerospace, and medical devices.
