Divided into manual and automatic two kinds.

Automatic placement machine is used to achieve high speed, high precision automatic discharge device affixed components, the entire SMT production of the most critical and most complex equipment. Pick and place machine production line is the main equipment, SMT Machines from the early development of low-speed mechanical SMT placement machine high speed optical alignment, to the multi-functional, flexible connection modular development.

SMT Machines as a high-tech products, safe and correct operation of the machine and people are very important.
Safe operation of the mounter most basic is the operator should determine the most accurate, should follow the following basic safety rules:
1. The machine operator should receive training in the proper way to operate under.
2. Check the machine, repair and replacement of parts or internal adjustments should turn off the power (the machine maintenance must be in pressing the emergency button or power off situation.
3. To make sure "read coordinates" and to make adjustments when the machine YPU (programming block) in your hands to stop the action at any time.
4. make sure "interlock" safety device to stop the machine at any time in order to remain effective, safety testing on the machine and so can not be skipped, shorted, otherwise prone to personal or machine accidents.
Allowing only one operator operates a machine 5. production.
6. During operation, make sure all parts of the body such as hands and first-class machine outside the range of movement.
7. The machine must be properly grounded <real ground, rather than the zero line>.
8. Do not use the machine body in a gas or very dirty environments.

Its population mostly use the sound quality is not required, and thus inexpensive ordinary monocular Bluetooth speakers make it easy for the public to buy.
Outdoor Monocular Mini Bluetooth Speaker
Since ordinary mini Bluetooth speaker is difficult to meet the requirements of the outdoor environment, so outdoor mini Bluetooth speaker will come into being. Its wireless, portable, outdoor use at home can be, can meet the basic requirements of waterproof drop resistance, to meet simple outdoor sports, but also due to the limitations of volume is too small, the sound quality can not be a major breakthrough, only in portability and a breakthrough on water drop, on life in general in three to five hours of battery life only for a short outdoor activities. Outdoor Portable Bluetooth Speaker as a transitional product, its price is relatively cheap. The main advantage of this type of speaker is compact, portable, easy to carry, but with the other side is a small sound in general, poor bass, battery life is short and other shortcomings.
