2. **Complex Production**
The production of multilayer PCBs is more challenging and requires more design time and meticulous manufacturing techniques compared to other PCB types. Even minor defects in PCB design or manufacturing can render the board ineffective.
3. **Limited Availability**
One significant issue with multilayer PCBs is the high mechanical cost required for their production. Not all PCB manufacturers have the necessary funds or equipment for this, limiting the number of manufacturers capable of producing multilayer PCBs. Therefore, it’s crucial to thoroughly assess a PCB manufacturer’s capabilities in multilayer PCBs before choosing them as a contract manufacturer.
4. **Need for a Skilled Designer**
As previously mentioned, multilayer PCBs require extensive design work in advance. Without relevant experience, this can lead to problems. Multilayer boards need careful interconnections between layers while managing crosstalk and impedance issues. A single design flaw can cause the circuit board to malfunction.
5. **Production Time**
With increased complexity comes heightened manufacturing requirements. This has become a major issue for the turnaround time of multilayer PCBs—each board demands substantial production time, leading to higher labor costs. Additionally, this may extend the period between placing an order and receiving the product, which could be problematic in certain cases.
6. **SMT Patch Processing**
However, these challenges are not mitigated by using multilayer PCBs. Despite their higher cost compared to single-layer PCBs, multilayer PCBs offer several advantages that outweigh these issues.
