Single-layer or single-sided PCBs are the most common type of board. These boards have a single conductive copper layer sitting above the substrate, with electrical components soldered to one side. There is an etched circuit visible on a single side of the board, with a single conductive layer, and paths that do not overlap. Single-sided PCBs function best for low-density design requirements and are used for basic electronics such as radios, power supplies, and calculators. They’re easy to manufacture, cost-effective, and simple to repair.
Double-layer or double-sided PCBs feature thin conducting material on the top and bottom of the board. With holes allowing the metal parts to connect from one side to the other, double-sided PCBs use through-hole or surface-mount technology to connect the circuits on either side, and lead components are installed through pre-drilled holes and soldered to pads on the opposite side. Surface-mount technology allows for the precise placement of electrical components, and these methods result in double-sided PCBs being much more versatile than single-sided options. Double-sided PCBs are used in cell phone systems, HVAC applications, and UPS systems, and are preferred for their low cost, compact size, increased circuit density, and design flexibility.
Multilayer PCBs feature two or more copper layers and three or more conductive layers. These boards are designed with double-sided conductive layers divided by insulating materials, bonded and laminated under high temperatures and pressure which ensures a stable final product with no air gaps. Multilayer PCBs are commonly used in mobile phones, laptops, GPS trackers, medical equipment, and other more complex circuits. They are compact, feature robust design options, have higher levels of flexibility, and are the preferred option for high-speed circuits.

Candor’s technology is modern and innovative, our competitors are 10 years behind us! This benefits our customers because we can produce what our customers can dream. We provide essential innovative solutions in Printed Circuit Boards that allow product innovations in ways that were never possible before.
More About Our Technology
Created in 1999, Candor is a response to 21st Century Customers who require new & innovative solutions to rapidly changing complex technologies. With twenty-five years of PCB build experience, we succeed beyond standard manufacturing methods and surpass limitations seen elsewhere in our industry.
Candor is the only manufacturer in the world to have perfected a liquid photo-imageable resist (PiP) in electrolytic form, used for all our production. This allows for a panel-plating process, which in turn means a highly uniform surface copper distribution, excellent impedance matching results, landless via formation, and superior fine line features. This process has replaced many undesirable products and chemistries from fabrication processes found in the majority of PCB shops around the world.
As an environmentally friendly company, Candor has eliminated the use of formaldehyde, EDTA, dry-film resists, ammonia-based etch chemistry, and tin-lead resists and our associated by-products. As an industry leader, we want to be your number-one choice for PCB creation and design.
More About Our History
Fast turnaround times are a standout feature of Candor, and we pride ourselves on lead times that outstrip our competitors and fulfill the needs of our customers.

We also provide fast, reliable shipping with updated delivery.
More About Our Quality AssuranceOur PCB assembly process occurs in four unique stages, where key elements and considerations must be made for single layer, double layer, and multilayer boards. Paste application, automated component placement, soldering, and inspection create your unique PCB, and each stage requires different equipment to ensure your PCB is built correctly, functions as intended, and meets our standards.
PCB assembly involves placing various electronic components on the board. The process applies a small amount of solder to the pads on the PCB before placing components. Then, a stencil is used to apply past to the board’s surface. This allows our Automatic Optical Inspection Machine and In-Circuit Test Fixture to make early tests and inspections of your board.
Our solder paste jet printer utilizes extreme precision, eliminating board transfer time whether it’s a single layer PCB or a multilayer PCB. The solder paste allows components to be attached, and an inspection ensures that the paste is evenly applied.
This stage features automated component placement, where a robotic hand accurately positions and mounts the surface-mount components of your PCB. These pieces of PCB use advanced algorithms and vision systems to identify each component’s location and orientation.
By using advanced, cutting-edge techniques, components can be precisely placed on the board. This technique improves the assembly process’s speed, accuracy, and reliability, reduces the need for manual labor, and increases the overall quality of the finished product.
When it’s time for soldering, electronic components and circuit parts on the PCB are conjoined by melting and fusing a metal alloy with a low melting point called a solder. There are other steps, such as adhesives or bindings, that ensure a proper flex adhesive is chosen so that your printed circuit board stays together.
Other epoxy-based laminates are used to assemble your PCB, and Candor utilizes special materials that ensure that boards meet our quality standards. For instance, Black FR4 is a substrate material used for high-performance applications that require excellent electrical and mechanical properties.
Inspection is the critical final step in Candor’s PCB assembly process. This involves examining the assembled board and ensuring it meets our quality standards. The inspection process helps to identify errors and defects and thwarts other issues that could impact the board’s functionality or reliability. We only deliver excellent, functional, dependable products to our customers.
