Flexible circuit board is a highly reliable and excellent flexible printed circuit board based on polyimide or polyester film. It has the characteristics of high density, light weight, thin thickness and good bending. By embedding circuit design on flexible thin plastic sheet, a large number of precision components are stacked in narrow and limited space to form a flexible circuit. This kind of circuit can bend at will, fold the weight light, the volume is small, the heat dissipation is good, the installation is convenient, broke through the traditional interconnection technology.

Single-sided flexible circuits are the simplest and there for cheapest, consisting of a single conductor layer on a flexible dielectric film with the option of a coverlay or semi flexible liquid photo-imageable solder resist (for some flex & stay applications). Parts of the flexible can be made more rigid by the use of additional stiffeners.
Double sided flexible PCB consist of two copper layers with a dielectric layer in between ,Normally connected with plated through holes, with the option of coverlay or semi flexible liquid photo-imageable solder resist (for some flex & stay applications). Parts of the flexible can be made more rigid by the use of additional stiffeners.
Multilayer flex PCB consist of three or more copper layers with a dielectric layer in between, normally connected with plated through holes, with the option of coverlay or semi flexible liquid photo-imageable solder resist (for some flex & stay applications). Parts of the flexible can be made more rigid by the use of additional stiffeners.
Rigid-flex PCB consist of a mixture of flexible copper conductor layers on dielectric film & rigid copper material, normally connected with plated through holes. Coverlay are applied to the flexible copper conductor layer & liquid photo-imageable solder resist applied to the rigid areas.
It is used to maintain the insulation between the circuit and each layer, commonly known as the FCCL substrate.
This is a non-essential structure. The main function is to mark the name and position frame of each part on the circuit board, which is convenient for maintenance and identification after assembly.
The circuit is used as a tool for conduction between the components. In the design, a large copper surface will be designed as a grounding and power supply layer. Lines and drawings are made at the same time.
The main factor that directly determines the quality of an FPC flexible circuit board is the surface treatment process. At present, the more common surface treatment processes are immersion gold, immersion silver, gold plating, tin plating, OSP, etc.
The FPC coverlay can also be called a protective film. The main function is to protect the copper foil from being exposed to the air, to avoid oxidation of the copper foil, to cover lines in the subsequent process such as surface treatment, and to act as a solder mask in SMT process.
The via hole can make the lines of more than two layers conduct each other.

Conformal coatings are widely used in PCBA applications, particularly in harsh environments with extreme temperature and humidity. These coatings provide excellent insulation, moisture-proofing, anti-vibration, dust-proofing, corrosion resistance, and more. This helps extend the life of the PCBA and protect it from external corrosion and contaminants. The conformal coating can be applied using either a brush or a spray method. The typical process involves coating side A, surface drying, coating side B, and curing at room temperature. The recommended coating thickness ranges from 0.1mm to 0.3mm, and all operations should be performed at temperatures above 16℃ and relative humidity below 75%.
After reflow soldering, it is crucial to inspect for missing components, correct placement, short circuits, and pseudo soldering. While the first three issues are easy to identify, pseudo soldering is more complex, often caused by insufficient solder, poor wetting, or defects in the pad design, PCB oxidation, or component quality. Pseudo soldering can be identified using online testers, visual inspection, or microscopes, and should be addressed immediately to prevent hidden defects. Causes include poor pad design, oxidized PCBs, insufficient solder paste, and defective components (e.g., oxidized or deformed). Solutions involve correcting pad design, cleaning or drying the PCB, replenishing solder, and ensuring component quality.
Rout Rules:When specifying a board edge, please ensure that if you are designing in Autotrax, Circuit Maker or Protel that the board edge is defined in Mechanical 1 layer.If you are panelizing your boards please ensure that there is a minimum of 100mil between board edges to allow for the router
The PCB industry, despite being technology- and capital-intensive, remains labor-intensive due to manual processes and pipeline operations, often requiring thousands of employees. The introduction of industrial robots into the PCB manufacturing process brings significant advantages, such as reducing labor costs, improving operational accuracy, enhancing product quality, and improving worker safety by minimizing exposure to hazardous chemicals and repetitive tasks. Robots also allow for 24/7 operation, greater production flexibility for small orders, and reduced material consumption through precision handling. In the long run, robot automation enhances the brand image, product quality, and competitiveness of PCB manufacturers.
SYS Tech has previously introduced shielding die wave soldering and through-hole reflow soldering for PCBA through-hole soldering processes. The immersion soldering process, which allows the soldering of joints ranging from 0.7mm to 10mm, is ideal for short pins and small pads, offering stable performance with reduced risk of bridging. When using immersion soldering, it is recommended to maintain over 5mm distance between adjacent solder joints, devices, and soldering tips. Key parameter settings include a soldering temperature of 275℃–300℃, an immersion speed of 20mm/s–25mm/s, an immersion time of 1–3 seconds, and a post-immersion speed of 2mm/s. The shock pump rate is determined by the number of welding nozzles.
FR-4 Copper Clad Laminate (CCL) materials are categorized into various levels based on quality and application. The A1 level CCL is designed for high-performance applications such as military, communications, and automotive circuits, meeting world-class standards. A2 level CCL is cost-effective, suitable for general computers, instruments, and advanced electronic products, offering balanced quality and competitiveness. A3 grade CCL is used in household appliances, computer peripherals, and general electronics, providing a competitive price for mass-market products. A4 grade is a low-end CCL material, still meeting performance needs for everyday electronics, with the highest cost-efficiency. Class B CCL, the most affordable, has poor quality stability, limiting its use to smaller circuit boards (less than 100mmx200mm) due to size instability.
