The pressure control device of the refrigeration system can make the unit work safely; All you need to know about the PCB control board. However, you know that if there is no flow control board, another situation may occur. Select the pcb control board, and you need to know what content.
Speaking of SMT processing factory, many people will be confused. Datong is a factory. It is seen from the familiar perspective. The components are all based on the PCB. There are no high and low components or their processing plants.
Basic process elements of SMT: solder paste printing.> Surface-mounted devices - When mounting components to the specified position on the surface of the circuit board, we should pay attention to the influence of the surrounding layout on the signal when laying out. The following points to be noted in detail when SMT mounting mainly refer to the mounting accuracy. We did not refer to the mounting position of the same component at the beginning.
● The mounting position is on the circuit board. On the same PCB, we can be sure of the mounting accuracy and requirements of the circuit board that has been processed from scratch.
● Mount components on the circuit board. The mounting method between plug-in components must be calibrated by the equipment to fully mount. This mounting equipment, which is the entire mounting process, occurs on the sub-circuit board, commonly known as three semi-horizontal mounting components (SMD yuan/piece), also known as three-axis precision components.
● Component programming: pipeline spacing, socket number, socket spacing, socket metric, connector material;
● Ensure that the components are firm and clear, and can be used for wide temperature sampling or automatic detection environment, even in low temperature and high cold environment in winter;

● Inspection and installation: the tube-to-temperature sampler shall be installed outdoors, rain-proof and anti-corrosion treatment, suitable for indoor thermostatic turbidizer and outdoor intercom;
● Rate switch: It is mostly used on printed circuit boards. Since the switch operates at high frequency, the braking resistance will consume energy when it is turned off, so the switch should be used for this equipment;
● Point function: the touch spring plate is used for the connection and disconnection of the load circuit, with the clearance between the spring plate and the contact point and the clearance between the contact and the contact conduction. This contact is used to control the contact of other models;
● Resistance in low on-state: please check one of the gold-plated contact models of conductive contactor!
● The contact number of the contact under the action of phase failure and the rated contact is poor, and generally there is no significant difference.
In terms of materials, there are general 1/3 type and general 1/3 type contactors. The universal type 8 contactor is used to control the C contact connection without touching the wire.
In recent years, it is often attributed to the cooperative contact of iron system and non-iron body. Type 8 contactor of type C is used to control the rotation of Z axis and Z axis, and the rotation of Z axis is very good. In this way, the sixth generation of 6-key contactor with specifications developed in this field has further expanded the scope of application of this product, and released relevant service functions towards it, opening up a new development space for the development of urban transportation.
Lehausen, C-type 6-code connector, high-speed output from 100kHz to 5kV, high-speed completion of travel. At present, it has been developed, and it is sufficient to meet the special requirements of users when designing other products with special structure. C-type coding connectors are widely used in petroleum, chemical, electric power, transportation, electric power, petroleum and transportation industries.
The performance of connectors is crucial for ship automation, civil technology, automatic testing and wiring harness interconnection. They are crucial to the electronic control system. Their importance means that under the action of water and water, the function of connectors can reduce wear and keep the minimum between circuits in case of failure.
The definition of sealed connector refers to the sealed connector used in automobile and industrial applications. Because they are a combination of structures, they should be widely included in the structure of the vehicle under external pressure.
A variety of connectors that can bring advantages are also available. For example, HS-MABLES is composed of multiple layers, which is suitable for flexible structures and converts storage space changes into vehicle applications, and provides special solutions.
Gaoke provides an incredible zero position surface contact option, providing high working strength without coupling.
The all-metal shell can be directly connected to the worker to wear the mold through the USB-RS232 interface. Even in high load applications, the true zero position surface contact is connected to the worker's contact, and the space interference caused by wrong operation is not allowed.
In order to simplify the maintenance settings, the designer also provided the use of GVSP2 hole on the PC to avoid long power consumption. All other standards provide a very Lod fork debugging tool for zero design. You can upgrade with one software or use a direct remote device for maintenance.
