Via-in-Pad Technology
Common Issues / SAYFU Solutions
Via-in-Pad Cost
SAYFU is one of the largest PCB fabricators in China, and is regularly studying new materials and methods to help save costs. Many suppliers of this technology have developed this specific niche. As a result, their customers must absorb the supplier’s entire overhead via the piece price.
SAYFU remains a production PCB supplier with a strong focus on prototyping through production of advanced technologies. However, our facility is also constantly processing higher volumes of standard technology PCBs.
As a result, our overhead is spread over a larger number of production panels and projects, allowing us to charge a fair and reasonable price to our customers that is often reserved of the high level of technology in the products we produce.
We have been producing PCBs with via-in-pad technology since 2002 and, along the way, have identified and addressed the most common root causes for yield loss.
Voids / Dimples
Through the use of vacuum tables and power squeegees, we have been able to fill up to 10:1 aspect ratio vias with no voiding.
Surface Planarity
Many of our competitors produce via-in-pad too intermittently to invest in the specialized equipment necessary to planarized via-in-pad PCBs with sufficient throughput and quality suitable for PCB assembly.
We have purchased and installed a Pola & Massa conveyorized planarizer that utilizes ceramic scrubbing rollers to ensure a high grade surface finish for via-in-pad applications.
