Hello everyone, today we will learn about a customer case of operating lithium battery protection board on the customized modules completed by small automatic smt machine line ,TVM925s pick and place machine ,stencil printer QP3250,T960 reflow oven and pcb conveyor .
The customer said that small machines like the TVM925s smt placer is easy to install, and they don’t require a relatively demanding site like the japanese brand large-scale placement machines. The small machines can be used directly on the passageway on the first floor, which is very suitable for him.The TVM925s software operating system is also very friendly, and you can start debugging by yourself after a little research.
The placement accuracy is also enough to match the board he developed. What he showed in the video the smallest component he uses is the 0402 package .
what is battery protection board ？
Battery protection board, as the name suggests, is mainly an integrated circuit board that provides protection for rechargeable (usually referred to as lithium batteries). The reason why lithium batteries (rechargeable) need protection is determined by their own characteristics. Due to the material of the lithium battery itself, it cannot be overcharged, discharged, overcurrent, short circuited, or charged or discharged at ultra-high temperatures. Therefore, the lithium battery components always appear with a protective plate with a sampling resistor and a current protector.
What is the function of lithium battery protection board ？
The protection function of lithium batteries is usually completed by the cooperation of the protection circuit board and current devices such as PTC or TCO. The protection board is composed of electronic circuits, which accurately monitor the voltage of the battery cell and the current of the charging and discharging circuit at all times in an environment of -40 ℃ to+85 ℃, and control the on-off of the current circuit in real-time; PTC or TCO prevents severe battery damage in high-temperature environments.Read more: SMT line case of operating lithium battery protection board

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 pick and place machine.
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.
