Multifunctional PCB Ruler 30cm

Description Multifunctional PCB Ruler 30cm Multifunctional PCB Ruler 30cm, it also integrates relevant information for PCB design such as angle gauges, devices, IC pin spacing tables, and more. Electronic enthusiasts in the design process in urgent need of a measurement tool can be set all the necessary functions. In addition to measuring the basic functions of millimeter and inch sizes, it also integrates relevant information for PCB design such as angle gauges, devices, IC pin spacing tables, Resistor and capacitor chip package, the commonly used diameter reference drill, line width size reference We printed this information on FR-4 gold-plated PCBs. R-4 gold-plated PCB, high-end atmosphere, high hardness, wear resistance Positive Specifications: The measurement length: 25cm Measuring length: 10 inches Commonly used IC package: 1.NAND_FLASH_TSOP48  2.QFP7X7-64   3.PLCC-20  4.SOP16  5.TSSOP24  6.SSOP8  7.SOP8 Commonly used CHIP component: 1.TO252-3  2.SOT223  3.SOT89-3  4.SOT23-6 5.SOT23-3  6.SOD123  7.SOD323  8.1210  9.3528  10.1206  11.0805 12. 0603  13. 0402  14.TO92 Common bore diameter reference dimensions (unit: mm): 3.0  2.5  2.0  1.5  1.0  0.8  0.5  0.4 Slot for hanging straightedge Back Specifications: Commonly used line width reference (unit: mm) Angle measurement: 180 degrees Device, IC pin spacing table: 0.5mm, 0.65mm, 0.8mm, 1.0mm, 1.25mm, 2.54mm; Common bore diameter reference dimensions (unit: mm): 3.0  2.5  2.0  1.5  1.0  0.8  0.5  0.4
