Older methods had problems like uneven coating and slow work. Using this method, companies like LT CIRCUIT make PCBs faster and stronger. It also works well for modern high-tech devices.

Key Takeaways

Horizontal Copper Sinking makes PCB production faster and more efficient.
Machines help apply copper evenly, making PCBs stronger and reliable.
This method is eco-friendly, using fewer chemicals and less waste.
It works well for factories needing to make many PCBs quickly.
Quality checks are important to ensure PCBs meet high standards.

Traditional Copper Sinking in PCB Production

Overview of the traditional copper sinking process

The old way of copper sinking has many steps. Each step is important to prepare the PCB and get good results. Here’s how it works:

Alkaline degreasing: This step cleans grease and dirt off the PCB. It also gets the holes ready for the next steps.
Micro etching: The surface is roughened to help copper stick better. This makes the copper layer bond strongly to the PCB.
Pre leaching: This step protects the palladium tank and helps activation work well.
Activation: Palladium is added to the PCB surface. This is a key step to start adding copper.
Degumming: The palladium is uncovered to help copper stick during the next step.
Copper precipitation: Copper is added in a chemical reaction, forming a thin layer on the PCB.

This method has been used for a long time. But it has some problems that make it less effective.

Challenges and limitations of traditional methods

Old copper sinking methods have trouble meeting today’s needs. One big problem is uneven copper layers. This can make the PCB weaker and less reliable. The process also takes a lot of time, slowing down production.

Another issue is that it needs a lot of manual work. This can cause mistakes and uneven results. It also creates more waste, which is bad for the environment. As technology grows, these problems make it hard for old methods to keep up with modern demands.

This is why new ideas like Horizontal Copper Sinking are important. They solve these problems and make PCB production faster and better.

Horizontal Copper Sinking Technology

Definition and principles of horizontal copper sinking

Horizontal Copper Sinking is a new way to coat PCBs. It adds an even copper layer by moving PCBs flat through chemical baths. Each bath has a job, like cleaning or coating the board. This flat movement helps cover the whole surface, including small holes.

This method uses controlled machines for better results. The PCB goes through special solutions that clean and coat it with copper. Keeping the board flat stops uneven layers, a problem with older methods. Machines make this process precise and reliable, perfect for advanced PCBs.

Tip: Horizontal Copper Sinking is great for modern devices needing accuracy.

Key differences from traditional copper sinking

Horizontal Copper Sinking is different from old methods in many ways. First, it keeps the PCB flat, unlike the vertical hanging in older ways. This stops gravity from causing uneven copper layers.

Second, it uses machines instead of manual work. Old methods need people to help, which can cause mistakes. The horizontal way uses machines for steady and accurate results.

Third, it works faster. Many boards can move through the system at once. This saves time compared to the slow, step-by-step old methods.

Lastly, it’s better for the environment. It uses less chemicals and creates less waste. Companies like LT CIRCUIT use it to make high-quality PCBs while caring for the planet.

Note: Horizontal Copper Sinking gives faster, better, and greener results.

The Horizontal Copper Sinking Process at LT CIRCUIT

Step-by-step process of horizontal copper sinking

At LT CIRCUIT, the copper sinking process is carefully planned. First, the PCB is cleaned with special solutions to remove dirt. This cleaning helps the copper stick well to the surface. Next, the board goes into a micro-etching bath. This bath makes the surface rough so copper can attach better.

After etching, the PCB is activated. A palladium solution is added to start the copper bonding process. Then, the board is placed in a copper sinking bath. Copper ions stick to the surface and fill the holes evenly. Finally, the board is rinsed and dried to make it clean and ready for the next steps.

This automated process avoids mistakes caused by manual work. Keeping the PCB flat ensures even copper layers. LT CIRCUIT meets the needs of modern electronics with this method.

Materials and equipment used in LT CIRCUIT's process

LT CIRCUIT uses advanced tools and materials for copper sinking. Alkaline solutions clean grease and dirt from the PCB. Micro-etching solutions prepare the surface for copper to stick. Palladium activators help start the copper bonding process.

The equipment includes machines that move PCBs flat through each step. This flat movement stops uneven copper layers from forming. Chemical baths with temperature controls make sure each step works well. Rinsing and drying machines finish the process, leaving the boards ready for the next stage.

Using high-quality tools and materials, LT CIRCUIT gets great results. This method speeds up production and makes strong, even copper layers.

Advantages of Horizontal Copper Sinking

Enhanced efficiency and production speed

Horizontal Copper Sinking makes PCB production faster and easier. It uses machines to do the work, so fewer mistakes happen. This also speeds up the process. PCBs move flat through the system, letting many boards be made at once. This method helps make more PCBs in less time without losing quality.

Machines used in this process need less fixing. This keeps the production running smoothly. Industries like electronics and telecom benefit from this speed. They need quick results to meet tight schedules.

Tip: Faster production helps meet demand and beat competitors.

Improved quality and uniformity of copper layers

Horizontal Copper Sinking creates even copper layers on PCBs. The flat position of the boards ensures copper spreads evenly everywhere. This includes small holes and edges. Even layers make PCBs stronger and better for high-tech uses.

Old methods often leave uneven copper because of gravity or mistakes. Horizontal Copper Sinking fixes this with precise machines and chemical baths. The result is a smooth, high-quality copper layer that works well for modern devices.

Note: Even copper layers improve performance and make PCBs last longer.

Scalability for high-volume production

Horizontal Copper Sinking works well for making lots of PCBs. Its machines can handle many boards at once, making it great for big factories. This is important in places like Asia-Pacific, where most PCBs are made. For example:

China makes over half of the world’s PCBs.
Suzhou factories produce 40,000 tons of copper agents yearly, meeting 15% of global needs.
Guangdong’s Pearl River Delta has over 200 factories, cutting delivery costs by 18-22%.

These examples show how this method supports large-scale production. Whether you need hundreds or thousands of PCBs, this technology works fast and keeps costs low.

Tip: Scalability helps your business grow while staying efficient.

Quality Control in Horizontal Copper Sinking

Why quality control is important

Quality control is key to making Horizontal Copper Sinking successful. It ensures PCBs, the heart of electronics, are reliable. Without checks, defects can harm how products work. Finding problems early saves time and money. Fixing issues later costs more and can lead to recalls.

Following industry rules is another reason quality control matters. It keeps your business safe from fines and legal trouble. It also shows customers your products are trustworthy and meet high standards. When PCBs meet expectations, customers are happier. This builds trust and brings repeat orders.
