Definition and function of resistorsA resistor is a basic component in electronic devices, widely used to control or limit the current in a circuit. The resistance value of a resistor determines the extent to which it impedes the flow of current. According to Ohm’s law (V=IR), the higher the resistance value, the smaller the current flowing at a given voltage, where V is voltage, I is current, and R is resistance.In electronic circuit design, resistors stand as one of the most fundamental passive components, whose performance directly impacts the stability and reliability of entire systems.

In today’s electronic product design, 4-layer 1.6 mm PCBs have become the preferred solution for many engineers. This structure strikes a perfect balance between complexity, cost, and performance, making it particularly suitable for medium-complexity circuit designs.Standard Stackup Structure of 4-Layer 1.6mm PCBThe standard 4-layer 1.6mm PCB typically adopts the classic “signal layer/ground layer/power layer/signal layer” configuration with the following arrangement:Top Layer (L1): Signal layer      (outer), for component placement and high-speed signal routingInner Layer 1 (L2): Ground plane      (GND), providing low-impedance return pathsInner Layer 2 (L3): Power plane      (VCC), for power distributionBottom Layer (L4): Signal layer      (outer), for auxiliary routing and component placementThis structure uses prepreg (PP, typically 2116 type, about 0.12mm thick) to laminate the layers together, forming a finished board with a total thickness of 1.6mm. A typical material thickness distribution example is as follows:LayerMaterial/DescriptionThickness (Example)Top LayerSignal layer (1oz copper)0.035mmPrepregDielectric (FR-4)0.2mmInner Layer 1Ground plane (1oz copper)0.035mmCoreDielectric (FR-4)0.8mmInner Layer 2Power plane (1oz copper)0.035mmPrepregDielectric (FR-4)0.2mmBottom LayerSignal layer (1oz copper)0.035mmHistorical Origins of 1.6mm Thickness as Industry StandardThe 1.6mm (approximately 63mil) thickness becoming an industry standard for PCBs is no coincidence but has deep historical roots. During the vacuum tube era, phenolic resin laminates were typically produced at 1/16 inch (about 1.6mm) thickness, and matching connectors and other components were designed for this specification, gradually forming a complete industrial chain standard.With technological advancements, although PCB thickness ranges have now expanded to 0.4-3.0mm or even wider, 1.6mm remains the default choice for most electronic products due to its good mechanical strength, manufacturing convenience, and cost-effectiveness. Especially for 4-layer boards, 1.6mm thickness provides ideal interlayer insulation and structural stability.Key Design Considerations for 4-Layer 1.6mm PCBImpedance Control and Signal IntegrityIn high-speed circuit design, impedance control is crucial. The 4-layer 1.6mm PCB provides clear reference planes for signals through dedicated ground and power layers, greatly simplifying impedance matching design. Typical design values include:Single-ended signals: 50Ω±10%Differential pairs: 100Ω±10%By precisely controlling trace width (e.g., 0.195mm), spacing, and dielectric thickness, engineers can easily achieve target impedance values. TUOGEE’s engineering team has extensive experience in impedance control and can provide professional advice for your design.Power Distribution and Decoupling DesignThe advantages of dedicated power layers include:Lower power impedance reduces voltage dropProviding uniform power distributionFacilitating placement of decoupling capacitorsIt is recommended to place decoupling capacitors of appropriate values near power pins to form a low-impedance power distribution network (PDN).Electromagnetic Compatibility (EMC) OptimizationThe stackup structure of 4-layer 1.6mm PCBs naturally provides good EMC performance:Ground layers provide electromagnetic shieldingReducing the loop area lowers the radiationFurther shielding optimization can be achieved by adjusting      prepreg thicknessMaterial Selection and Performance ParametersCore Material OptionsFR-4: Most commonly used substrate,      offering good mechanical strength and electrical performance with high      cost-effectivenessHigh-frequency laminates: Suitable      for GHz-level high-frequency applications with a more stable dielectric      constantMetal-core substrates: Excellent      thermal performance, ideal for high-power applicationsCeramic substrates: Perfect choice      for ultra-high frequency and high-temperature applicationsKey Performance ParametersDensity: 1.05-1.2g/cm³ (240x420mm      board weighs about 100g)Copper thickness: Typically 1oz      (35μm), can increase to 2-3oz for high-current areasTemperature resistance:      Conventional FR-4 Tg value 130-180°C, high-temperature models can exceed      200°CSolder mask: Liquid epoxy or      polymer, typically 15-25μm thickComparison and Applications of 4-Layer PCBs with Different ThicknessesWhile 1.6mm is the industry standard, other thicknesses have their applicable scenarios:ThicknessCharacteristicsTypical Applications0.8mmSpace-saving, more flexiblePortable devices, small consumer   electronics1.0mmBalanced thickness and strengthIndustrial control modules, communication   equipment1.2mmModerate mechanical strengthAutomotive electronics, medical devices1.6mmStandard thickness, best   cost-performance ratioMost consumer and industrial   electronics2.0mm+Ultra-high mechanical strengthPower modules, heavy-duty equipmentIt’s worth noting that non-standard thicknesses (such as 0.8mm or 2.0mm) may require additional costs and should be considered comprehensively at the design stage.Manufacturing Process and Quality Control PointsThe manufacturing process for 4-layer 1.6mm PCBs includes:Inner layer pattern transfer and etchingLamination (180-200°C, high pressure)Drilling (mechanical or laser)Hole metallization (electroless copper plating)Outer layer pattern transferSolder mask and surface finishElectrical testing and final inspectionTUOGEE employs advanced AOI (Automated Optical Inspection) and flying probe testing to ensure the quality of each PCB, with impedance control accuracy reaching ±7%, far exceeding the industry standard of ±10%.Frequently Asked QuestionsQ: Why do most interface standards adapt to 1.6mm thickness? A: This is an industry standard formed historically, as early connectors were designed for 1/16 inch (≈1.6mm), and the supporting industrial chain developed accordingly.Q: How much more expensive is a 4-layer 1.6mm PCB compared to a double-sided board? A: Typically 1.5-2 times the cost of double-sided boards, but through design optimization (such as standard stackup) and volume production, TUOGEE can offer highly competitive prices.Q: How to determine whether my project needs 1.6mm or other thicknesses? A: Consider factors including: mechanical strength requirements, connector compatibility, thermal requirements, and cost budget.
