smt pick and place machine -what's the resistor functions ?

Resistance (resistance), we often call it R in daily life, the unit is ohm, if you want to define the resistance, it is the size of the resistance of the conductor to the current, the resistance is a current limiting element, the conductor’s current resistance If the blocking effect is large, we say that its resistance is large, otherwise, it is said that its resistance is small. But resistance will not disappear because there is no current flowing through the conductor. Resistance is an inherent property of a conductor. Even if there is no current flowing through the conductor, its resistance still exists.Today author from QiHe smt pick and place machine sharing you with the details .

Classification of resistance

Resistance is just a general term. After a deep understanding of it, you will know that there are many kinds of resistance, which can be divided into:
Fixed resistors, variable resistors, special resistors, RT-type carbon film resistors, RJ-type metal film resistors, RX-type wirewound resistors, chip resistors, high-power resistors, and low-power resistors. Do you really know the various functions of resistors?

partial pressure

When a resistor and another component such as a bulb are in series in a circuit, the current flowing through the resistor and the bulb is the same, and the sum of the voltages across the resistor and the bulb is equal to the total voltage across the resistor and the bulb as a whole. At this time, the resistor acts as a voltage divider.

electric shunt

When a resistor and another component such as a bulb are connected in parallel in the circuit, the voltage across the resistor is the same as the voltage across the bulb, and the sum of the current flowing through the resistor and the current flowing through the bulb is equal to the total current flowing through the resistor and the bulb . At this time, the resistor acts as a shunt.

impedance matching

Impedance matching refers to the process of using some methods to make the load impedance and the internal impedance of the excitation source adapt to each other in order to obtain a working state of maximum power output during the signal transmission process. And one of its methods is to realize by changing the impedance. In this case, the resistance plays the role of its impedance matching.

filtering

In the charging and discharging circuit composed of a resistor and a capacitor in series, in this infinite cycle of charging and discharging, we call the role of the resistor as a filter.

What is SMT in engineering?

Surface mount technology is a part of the electronic assembly that deals with the mounting of electronic components to the surface of a PCB. Electronic components mounted this way are called surface-mounted devices (SMD). SMT was developed to minimize manufacturing costs while making efficient use of board space.Qihe SMT company develops and produces all kinds of SMT equipment suitable for world wide market, including pnp machine,reflow oven,stencil printer,pcb handling machines,and other products.

What is SMT in programming?

Offline Automated Programming vs Inline SMT Programming
Qihe pick and place machine can be programmed directly on the SMT equipment .
Or Coordinates can also be imported csv file through programming software.
Currently supported software such as protel,DXP,Altium Designer,Pads,Candes,proteus,DXP.
Inline SMT programming is a solution to consider for narrow segments of device programming requiring short programming times, with medium to high volume, for just one device type.

WHAT IS SMT pick and place machine？

SMT (Surface Mounted Technology) is a comprehensive system engineering technology, which covers substrates, design, equipment, components, assembly processes, production accessories and management. When it comes to SMT pick and place machines, the automatic SMT production line requires automatic loading and unloading machine, automatic solder paste printing machine, placement machine, reflow soldering machine, AOI inspection equipment, conveyor,connecting table, etc. For these SMT assembly line equipment, Qihe SMT can offer you machines in prototype SMT line, small SMT production line, mass production SMT line at low SMT line cost. Contact us now if you are interested.

WHAT IS SMT ASSEMBLY LINE？

With the development of technology, future electronic products will be lighter, smaller and thinner. Traditional assembly technology can no longer meet the requirements of high-precision and high-density assembly. A new type of PCB assembly technology-SMT (Surface Mount Technology) has emerged. SMT Assembly is the use of automated machines to assemble electronic components on the surface of the circuit board. Its density, high speed, standardization and other characteristics occupies an absolute advantage in the field of circuit assembly technology. In addition, SMT assembly has a wide range of uses.
