Insulation resistance (IR) is a measurement of how good or bad your insulation is, which can help give you an overall assessment of your electrical equipment’s health. By the way, no insulation is perfect—with infinite resistance—but good insulation has a relatively high resistance to current.Today qihe smt pick and place machine sharing what is SMD insulation resistance testing?
Portable insulation resistance testers and megohmmeters are designed to help prevent hazards such as electric shock and short-circuits caused when the insulation in electrical devices, parts, and equipment used in industrial plants, buildings, and other settings degrades over long periods of use.
Degradation of the insulation between charged and non-charged portions of electrical devices and equipment utilizing the type of structure illustrated in Figure1 poses the risk of a ground fault or electric shock. Degradation of the insulation between two or more charged potions as shown in Figure 2 poses the risk of a short-circuit.
Higher insulation resistance values indicate more effective insulation.
Insulation Resistance Tester Product List
Insulation testers: Rated standard measurement voltage and example uses
When using an insulation resistance tester to measure insulation resistance, Japanese standards* require certain voltage values to be applied by the instrument for certain measurement targets, as shown in the table.
It is necessary to select from the multiple application voltage values (rated measurement voltages) that are provided by the insulation resistance meter based on the target:
Single-range insulation testers: Insulation resistance meters that can only generate one rated measurement voltage
Multi-range insulation testers: Insulation resistance meters that can generate two or more rated measurement voltages
Since different insulation testers provide different combinations of rated measurement voltages, it is necessary to choose an instrument that provides the combination of values that is best suited to the application at hand.
*The table lists values from Japanese standards.
Please note that these values vary by country.

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 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.
