Introduce:
When manufacturing printed circuit boards (PCBs), ensuring drilling accuracy and hole wall quality in a 4-layer PCB stack is critical to the overall functionality and reliability of the electronic device. Capel is a leading company with 15 years of experience in the PCB industry, with quality control as its core focus. This blog aims to provide you with valuable insights into how to achieve impeccable drilling accuracy and hole wall quality in a 4-layer PCB stack-up, while also highlighting Capel’s expertise and reliable turnkey PCB solutions.
1. The importance of drilling accuracy and hole wall quality in 4-layer PCB stack-up:
Drilling accuracy and hole wall quality are key factors that directly affect the performance of a 4-layer PCB stack. Poor drilling accuracy can lead to component misalignment, impedance issues, and signal integrity issues. Likewise, insufficient hole wall quality can affect the effectiveness of plated through hole (PTH) connections, leading to reliability issues and reduced electrical performance.
2. Choose the right drilling equipment and technology:
To ensure drilling accuracy, invest in high-quality drilling equipment that allows precise control of drilling speed, depth, and alignment. Automatic drilling machines with advanced features such as laser-assisted drilling and computer-controlled precision are highly recommended. Additionally, consider laser-drilled microvias for advanced multilayer boards as they offer superior precision and reliability.
3. Best stacking design:
Proper stack-up design plays a vital role in achieving drilling accuracy and hole wall quality. Please consider the following tips:
- Minimize the number of signal layers to reduce drilling complexity.
- Keep core thickness uniform to prevent drilling holes from tilting.
- Use a balanced copper distribution to avoid bending and warping during drilling.
- Place high-speed signals and sensitive components away from the drilled area to minimize the risk of electrical interference.
4. Precision PCB manufacturing process:
Capel has 15 years of experience and follows strict manufacturing processes to ensure drilling accuracy and high quality hole walls in 4-layer PCB stack-ups.
