commonly used IC package: 1.SSOP16, 2.QFN32, 3.SOP16, 5.QFP32 4.TSSOP28
R-4 gold-plated PCB, high-end atmosphere, high hardness, wear resistance
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.
