Mixed Laminate Multilayer PCBs
Consisting of multiple laminates and differing dielectric constants, this multilayer (displayed above) is a mixed-dielectric printed circuit board.
Mixed Laminate Multilayer PCBs
Mixed laminate multilayer PCBs are ideal for complex and high-speed circuit designs that require different dielectric constants. They are composed of multiple layers of different laminates, allowing for precise control of impedance, signal integrity, and heat dissipation. The different layers of mixed laminate multilayer PCBs can be interconnected using vias and buried vias, providing a high degree of routing flexibility.

About SprintPCB
We can provide competitive prices and guarantee the quality requirements of customers without excess quality. Our technical level can meet most of the industrial control and consumer products.
Quality Assurance System
SprintPCB has established a rigorous quality assurance system that spans every stage from customer requirements to product delivery, ensuring the fulfillment of high standards of customer requirements.
Audit
Specifically for products with special requirements, the company has an Advanced Product Quality Planning (APQP) team, which conducts Failure Mode and Effects Analysis (FMEA) to thoroughly study potential failure modes and develop proactive countermeasures to ensure product quality. Developing control plans and implementing Statistical Process Control (SPC) are key steps in preventing potential failures. In addition, measurement instruments undergo Measurement System Analysis (MSA) certification to ensure measurement accuracy. For cases requiring production approval, production part approval process (PPAP) documents are provided to ensure production confirmation.
Inspection
Quality assurance covers incoming, in-process, and final inspections, as well as product review. Customer-provided data and manufacturing instructions undergo rigorous review, and raw materials are strictly controlled. During production, operators conduct self-inspections and collaborate with QC for sampling inspections. The laboratory inspects process parameters and performance. Finished products undergo 100% electrical performance testing and full inspection for appearance, with sampling inspection for appearance and dimensions to ensure product perfection. Directed inspections for specific projects are conducted based on customer requirements.

"I am extremely satisfied with the quality of the PCBs you manufacture. The solder pads on each board are very smooth and the connections are very strong. I have worked with other manufacturers before, but the quality was always subpar. Since switching to SprintPCB, the quality of my projects has significantly improved. Thank you for your outstanding manufacturing process!"
