How to Achieve 4-Layer PCBs in a Single Day – A Step-by-Step Checklist

From Design to 4-Layer PCB in One Day: A Step-by-Step Teaser

With the right system in place, achieving high-quality 4-layer PCBs in just one day is no longer a dream – it's a reality. Discover how in-house prototyping can transform your development timeline and give you an edge in your research and design projects. Contact our experts and speed up your PCB-Prototyping process.

Step-by-Step Overview 

Step 1: Import Your CAD Design 

It may sound easy, but many programs are not user friendly. To work fast the first step in the process must be already free of barriers. It is fundamental to import your CAD design into intuitive software. So, the setup is straightforward and requires no advanced training. LPKFs’ software will automatically guide you through the necessary configuration and speed you up. 

Step 2: Structure the Inner Layers 

Once your design is loaded, the software aligns your layers and prepares them for precision structuring. LPKF Laser systems are famous for fast and precise structuring. In just a few minutes, your inner layers are ready for the next step. 

Step 3: Press the Layers Together 

With the inner layers structured, the next step is to press them together. This process ensures that the layers are aligned and securely bonded. The Multipress from LPKF is known for its precision and flexibility. That makes the process fast and easily repeatable. Another benefit: perfect process integration with LPKF tools. No time is wasted, ready for further refinement. 

Step 4: Drill and Plate 

After the pressing stage, the PCB undergoes drilling to create vias and connections. The plating process follows, ensuring robust electrical connections between layers. For highest precision, reliability and a fast result there is no way around a laser solution from LPKF. 

Step 5: Structure the Outer Layers 

The final stage involves structuring the outer layers of your PCB. LPKFs’ precision laser tools carefully cut and shape the outer layers to match your design, completing the prototyping process.
