What are the Types of SMT Package

图片
          SMT package not only plays the role of placing, fixing, sealing, protecting the chip and enhancing   the electrical   and thermal performance, but also serves as a  “ bridge ”  between the internal circuit of the chip and the external circuit. Do you know what types of SMT package are there?   1.  QFP Package QFP package is a quad flat package, which is one of the main packaging forms of SMT integrated circuits. The leads come out from four sides in a seagull wing (L) shape. There are three types of base materials: ceramic, metal and plastic. In terms of quantity, plastic package accounts for the vast majority. When the material is not specifically indicated, in most cases it is plastic QFP.       2.  PLCC Package PLCC is a plastic leaded chip carrier package for an integrated circuit.   Its leads hook back inward and are called hooked (J-shaped) electrodes.  Most of the integrated circui...

Application of Underwater Disinfection Light PCB in Home Aquarium

图片
          As people ’ s quality of life continues to improve, more and more households  begin to raise  ornamental fish,  and  home aquariums   have become   a popular choice for   home   decoration and leisure. However, maintaining water quality in aquariums has long been a challenge for fish enthusiasts.  E xcessive growth of bacteria and algae in the water not only affects water quality but also threat en the   health   of the fish . The emergence of underwater  disinfec tion l ight   PCBs offers a new solution to this  problem . With their efficient sterilization capabilities and precise control performance, they show great application potential in the home aquarium  filed .   1.  Working Principle of Underwater  Disinfectio n L ight   PCB Underwater disinfection light PCBs are primarily equipped with ultraviolet (UV) light tubes or LED light beads, and use sp...

The Critical Role of Medical PCB in Surgical Lighting

图片
          In the medical field, the quality of surgical lighting directly impacts the success of an operation and the safety of the patient. Bright, uniform, and stable illumination is essential for surgeons to observe the surgical area precisely and perform procedures with accuracy, minimizing risks. As a core component of surgical lighting equipment, medical PCBs play an indispensable role with their exceptional performance and highly integrated design.   1. Surgical Lighting Under Strict Standards Surgical lighting devices must meet extremely stringent requirements. First, they must offer high brightness and excellent color rendering to ensure surgeons can clearly distinguish tissue colors and fine structures. Second, the light must be distributed evenly to avoid shadows that could obstruct the surgical field. Furthermore, the lighting equipment must offer light stability, ensuring consistent illumination throughout prolonged surgical procedures. Gi...

What is the Process of PCB Solder Mask Technology

图片
          The purpose of the solder mask is to prevent conductor from being stained with tin, prevent short circuits between conductors caused by moisture, chemicals, etc., prevent circuit interruption and insulation caused by poor operation during production and assembly, and resist various harsh environments. It is also used to ensure the functionality of printed circuit board.   So do you know what the process of this technology is?   1.  Mixing of  Solder Mask Inks The mixing of solder mask ink can be done by manual stirring, mechanical stirring and oscillation. Some solder mask inks need to be added diluent to reduce viscosity. The ink needs to be left for a certain period of time after mixing, usually more than 15 minutes. The purpose is not only to maintain the temperature and viscosity, but also to facilitate the escape of air brought in during stirring.     2.  Pretreatment Pretreatment refers to removing oxides, ...

Application of Automotive PCBA in Body Electronic Systems

图片
          During the operation and use of a  car ,  the  body electronic system  undertakes the important task of  ensuring   the basic   functions   of the vehicle   and  improving   driving comfort and safety. As a core component within these systems, automotive PCBA (Printed Circuit Board Assembly) is deeply involved in the operation of  every aspect . 1.  Lighting  C ontrol  S ystem Automotive PCBA acts as the  “ brain ”  of intelligent lighting control. In automatic headlight systems, it interfaces with ambient light sensors to detect real-time external lighting conditions. When the light dims, the automotive PCBA quickly processes the signal from the sensor and controls the headlights to turn on automatically; when the light becomes brighter, the headlights can be turned off in time without the driver's manual operation.     The  realization of  ad...
