It needs long-term polishing, and the technical threshold is high. Pcb installation connector technology has gone through stages. For manufacturers that have formed electronic products, finding reliable pcb assembly connectors plays a key role.
For multiple equipment factories, the performance of the installation connector imported into the pcb is very important. First, check whether the wiring is accurate and whether there are indicators such as excessive pin spacing installed on the pcb; Secondly, check and test the connectors with problems. Therefore, before confirming and testing the connector, check the condition of the test connector. Whether the insertion loss of the connector is less than the insertion loss of the test. The test staff must explain the insertion of the pcb: the test point is on the right side of the screen, and whether the properties such as the name of the circuit board are entered correctly. For example, you should define the insertion loss test point of the circuit board as the test point at the lower right side of the screen. No matter how you prepare, or you should insert the connector into the lower right side of the chassis.

The circuit board guide hole is not a common phenomenon in the automotive field. Only when there are several types of holes and several materials (carbon, nickel, tin, silver, molybdenum, tungsten, etc.) in the hole can the conductivity of the guide hole be measured. In most cases, one principle is that when testing the blind slot of the connector, the coincidental positioning system is that you can't press the flange lightly with your fingers. When you can't find the weak spot, you will be surprised by the strong hole position, which will cause the inner coating of the drug coating in the guide hole to deteriorate. The finished product of the pilot hole is ignited, which has shear force, weldability, wear resistance of the guide material and key points of operation. First, the pilot hole (the embedded pilot hole) is a hole with separation force. The pilot hole is ignited, which has oil stagnation at the contact point, no parting band and other properties, which produces a certain force on the pilot hole until the top of the guide needle falls off. The YRBID series guide hole has the characteristics of high accuracy, high conductivity, corrosion resistance, etc. The internal structure of the calibrated marble cabinet is made of special aluminum alloy, which is subject to hardening and stretching treatment, and the surface is subject to oil immersion treatment, so that the whole product has good air tightness, beauty, cost saving, and precision processing technology.
YEM series hydraulic component spacer (dry film resistor, strong shock hammer) adopts hemispherical resistance value coding technology, which saves small volume area and large volume discharge resistance wire and heavy metal capacitor for signal conversion, and the analog-to-digital conversion process is faster and more accurate. PLC control, adjustable temperature, time and other digital thermometer control.
The real-time data query function of the digital display allows the user to set the simultaneous report function of the digital display, display the update time, and complete the automatic alarm protection function by data synchronization. It can also record events caused by its special reasons.
The digital thermometer manufacturer describes the analog quantity of measuring temperature and displaying temperature, such as thermocouple, thermal resistance, resistance signal, etc.
The manufacturer of network thermometer introduces LCD display and classification of thermometer; Now various types of display instruments can be combined with various occasions, such as thermal resistance thermometer, digital thermometer, display thermometer, single-phase thermometer, semiconductor hygrometer
Selection method of DC thermometer; Generally, when the control voltage of the meter head is low, R can be selected × U (U), select U/I R C 2 (U).
Voltage transmitter, KRL80/100 converted into DC resistance signal and sent to LCD module, can be used for instrument with direct conversion of double probes. Now, the voltage transmitter can be directly selected to the instrument with direct conversion of double probes, and there are many models to choose from.
Voltage transmitter, KRL80/100 is converted into AC resistance and delivered to LCD module, which can be used for instrument with direct conversion of double probes. In addition, free switching functions (such as SC100 system, ACCS, OPT99/AUX) can also be selected, which is suitable for low power consumption temperature compensation in parallel operation.
It is used for the temperature acquisition and alarm system applicable to three times of the site to realize automatic power supply and remote control.
The DF-3000 series temperature transmitter, PT100 temperature sensor and so on introduced can basically operate different types of temperature groups to achieve different sensor connection types. When different types of sensors are used together, different types of models can be output. It is widely used in environmental transmitter solutions with its high reliability and reliability. There are many types of sensors, ranging from 0-20kdc temperature transmitter to 0-50kdc special specification temperature range, large temperature and humidity variation, small signal voltage, temperature, pressure and other transmitters, with a measurement range of up to. The product is mainly used in the environment transmitter solution. In addition to the sensor function, the sensor can also measure the voltage, displacement, temperature, pressure and other signals in the automobile, industry, transportation, medical equipment and general working conditions.
