Electric suction pen has built-in vacuum pump and it needs no external vacuum system. Electric suction pen can continue working more than 1000hours, which has strong suction, and two branch suction pens can work at the same time. It is produced by electrostatic materials, which can make sensitive elements avoid electrostatic damage. Vacuum suction pen can be divided into pneumatic suction pen and manual suction pen. The source of pneumatic suction pen requires 4-6 kg of compressed air, and the p...(more)
Vacuum suction pen, which looks like a pen, is a small pneumatic tool. It consists of a plastic or a rubber shell, a vacuum generator (pneumatic), a vacuum chuck, an elbow and a reel (pneumatic), and it can be flexibly used for assembly of small parts. Vacuum suction pen can be divided into two categories: pneumatic suction pen and manual suction pen. Air supplyrequirement of pneumatic suction pen is 4 to 6 kg of compressed air. The power of manual suction pen is the rubber bladder. Pneumatic su...(more)

DC-DC converter is a voltage converter that changes input voltageinto output fixed voltage. The DC-DC converter can be divided into three categories: step-up DC-DC converter step-down DC-DC converter and step-up and step-down converter. According to the demand, there are three types of control to choose:PWM with high efficiency has good output voltage ripple and noise; even after long time use, PFM has the advantages of small power consumption, especially when the load is small; PWM/PFM can achi...(more)
Thermistor has wide applications in many fields, and the following is about its applications of food, medical and automobile. (1) The thermistors application in food and drug field: Food and drug industries need temperature control to ensure the quality of products. In order to avoid partial or total loss of effective availability of drugs, there are a lot of drugs in transit needing accurate control of the temperature and humidity. (2) The thermistors application in medical field: Human often n...(more)
The NTC thermistor is a thermistor with negative temperature coefficient and it has high performance ceramics near theoretical density structure by using a single high purity material. Therefore, at the same time with realizing miniaturization, it also has the small fluctuation characteristics of resistance value and temperature and fast response characteristic, which can take the high sensitivity and high accuracy detection. NTC is the abbreviation of negative temperature coefficient, which ref...(more)
Thermistor is a kind of sensitive element, and according to the different temperature coefficients, thermistor can be divided into positive temperature coefficient thermistor (PTC thermistor) and negative temperature coefficient thermistor (NTC thermistor). The typical characteristic of the thermistor is sensitive to temperature, and different temperatures show different resistance values. At the higher temperature, the resistance value of PTC thermistor is larger, and NTC thermistor is lower, w...(more)
Thermistor is a kind of sensitive element. There are two kinds of thermistors based on different the temperature, which are PTC and NTC. It has a typical characteristic that it is sensitive on temperature. It shows different resistance value when it is under different temperature. When the temperature goes up, PTC is with higher resistance values while the NTC thermistor is on the opposite. But both of them belong to semiconductor apparatus. Main characteristic of thermistor a.It has very high s...(more)
