How to Protect Your Flex Circuits: Strain Relief and Tear Resistance StrategiesFlexible circuits—such as FFCs, FPCs, and rigid-flex assemblies—offer unparalleled design freedom in compact and dynamic electronic applications. However, their inherent flexibility makes them susceptible to mechanical stresses that can lead to failures like tearing, delamination, or conductor fatigue. Implementing...
When working with high-voltage circuits, design priorities shift. While many PCBs focus on high-speed signaling, impedance control, or component density, high-voltage designs prioritize safety, insulation, and spacing. Whether you're developing an industrial power controller, EV subsystem, or medical device, successful high-voltage PCB design demands a clear understanding of creepage, clearance,...
There was a time when business success was measured by how much a company could do in-house. From raw material procurement to delivery, fully vertically integrated corporations—think Ford or General Electric—dominated. The logic was simple: control every step, minimize risk. But that model no longer fits today’s fast-changing environment. The most...
When designing flexible circuits, especially those with irregular shapes, it’s easy to overlook how layout decisions impact manufacturing efficiency. But how your parts are nested within a panel directly affects both material waste and cost. That’s why it’s important to consider panel optimization early in the design process—not just during...
In multilayer PCB fabrication, what connects copper layers together isn’t just glue—it’s carefully engineered dielectric materials that control signal integrity, insulation, and mechanical performance. Among these, prepreg plays a critical role, serving as both an adhesive and an electrical insulator between copper layers. Whether you’re working on high-speed digital signals, RF layouts,...
For engineers balancing performance, flexibility, and cost, Flat Flexible Cables (FFC) remain one of the most efficient interconnect solutions in electronics today. Their simple structure, adaptability, and low manufacturing cost make them ideal for countless applications—from consumer electronics to industrial controls, smart home, industrial equipment, vehicles, electric...
In PCB manufacturing, solder mask isn’t just about making a board look green—it’s a functional layer that protects copper traces, prevents solder bridging, and improves overall assembly yield. But not all solder masks are created equal. From rigid PCBs to flexible circuits and high-density designs, the type of solder mask used—and...
Printed Circuit Board (PCB) manufacturing involves precise processes, not just in design and component assembly but also in how the final boards are separated from their manufacturing panels. At PICA Manufacturing Solutions, we use various depaneling techniques to ensure efficiency, accuracy, and cost-effectiveness. The three primary methods—V-scoring, routing, and die...
Conductive Inks and Their Role in Flexible and Printed ElectronicsAs electronics continue to evolve beyond rigid, boxy enclosures, the materials and processes used to build them are changing too. Conductive inks are a key enabler of this shift, offering engineers the ability to print circuitry directly onto thin, flexible, and...
Selecting the right base material for a PCB is never a simple choice. The properties of the substrate affect everything—from thermal stability to dielectric performance, mechanical strength, and manufacturing compatibility. Four standard materials dominate PCB fabrication: FR-2, FR-4, CEM-1, and CEM-3. While all of them provide insulation and structural integrity,...
FPC (Flexible Printed Circuit) manufacturing has evolved significantly, with both panel-based and roll-to-roll (RTR) processing methods widely used. Each method has its own advantages, limitations, and specific applications, particularly when manufacturing extra-long flex circuits. Below is a comparison highlighting capabilities specifically relevant to producing extra-long FPCs depending on application needs,...
Whether you're designing for a high-durability dynamic application or a compact static installation, every detail matters—from copper type and thickness to stackup design and layer placement. These design elements directly influence the PCB’s flexibility, durability, and long-term performance. For electrical and mechanical engineers alike, mastering these principles is key to...
