The development history of SMT surface technology Surface mount technology is developed from the manufacturing technology of component circuits. As early as 1957, the United States made micro-electronic components called Chip Components, which were assembled on the surface of printed circuit boards. In the mid-1960s, the Dutch Philips company successfully developed and researched surface assembly […]

Definition of SMT surface   technology Modern high-performance electronic products generally rely more and more on the rapid development of computer technology, the popularization of LSI (Large Scale Integrated Circuit), VLSI (Very Large Scale Integrated Circuit) and PCB (Printed Circuit Board). At the same time, the requirements for PCB are getting higher and higher. The chipization […]

The components in the integrated library have integrated information, including schematic symbols, PCB packaging, simulation and signal integrity analysis, etc. The integrated library exists in an uneditable form. All model information is copied to the integrated library. If you want to modify the integrated library, you need to modify the corresponding source file library first, […]

About digital oscilloscope measurement examples Before the digital oscilloscope takes measurements, the attenuation coefficients of the CHI and CH2 probes must be set consistent with the attenuation coefficients of the switch on the probe. For the switch attenuation coefficient setting of the CHI and CH2 probes, please refer to the probe compensation operating instructions in […]

Advanced application of SMT digital oscilloscope 1. Advanced applications of vertical systems (1) Channel settings. The vertical menus of the CH1 and CH2 channels of the oscilloscope are independent. Each item must be set separately for a different channel, but the items and operation methods of the two channel function menus are completely the same. […]

The essentials and precautions for the use of digital oscilloscopes (1) Signal access method. Take the CH1 channel as an example to introduce the signal access method. ① Set the switch on the probe to 10x, align the slot on the probe connector with the CH1 socket and insert it, and then turn it to […]

Introduction to the operation of the front panel of the digital oscilloscope The front panel of DS1000 digital oscilloscope can be divided into 8 areas according to its functions, LCD display area, function menu operation area, common menu area, executive button area, vertical control area, horizontal control area, trigger control area, signal input/ Output area, […]

What is probe compensation When connecting the probe to any input channel for the first time, you need to adjust the probe compensation to match the probe with the input channel to prevent measurement errors or errors. Taking channel 1 as an example, the steps of probe compensation adjustment are as follows: (1) Set the […]

Voltage measurement method Before measurement, adjust the brightness and focus to the best state to facilitate the readout, and the waveform display as large as possible to reduce the time error; if using a probe, check the capacitance correction. (1) Measurement of DC voltage. Put the AC-GND-DC switch to GND, the position is at zero […]

The functions of each knob of the 6502 dual-trace oscilloscope The 6502 dual-track oscilloscope can not only perform single-track display, but also display the instantaneous process of two different electrical signals on the screen at the same time, as well as display the waveform of the superimposed two signals. The instrument has the characteristics of […]
