CLICK→https://www.jrpanel.com/T Circuit design software is widely used, and modern circuit design cannot do without circuit design software. Among many circuit design software, protel is a commonly used one. In order to enhance everyone's understanding of circuit design software and protel, this article will introduce how to convert Protel 99se design into PCB projects in DXP based on this circuit design software . In addition, this article is only the first one, please refer to the next one for more content. 1. Generate the project Simply open the database file in the DXP menu, and you can convert a 99SE database file into a project in DXP. Make sure this operation starts a two-step process. First, the contents of all database files are placed in a new Windows folder (has the same name as the database file and stored in the same path). Secondly, some nearby files are generated and opened in DXP, which is a project group file with several independent project files. When your 99SE d...

It is widely used in industrial control, electrical measurement control and other fields.   The picture shows the appearance of the membrane switch panel of the intelligent digital measurement and control instrument.   There are four colors: light gray, dark gray, blue, and white. Light gray is used for decoration, dark gray is used as the main background, blue is used as the button area, and white is used as the color of text and instructions. So there are 4 colors in total.In the middle is a rectangular transparent window, and there is a small rectangular transparent window at the bottom right of the rectangular transparent window. Below the rectangular transparent window is a line of white text, which is the English of Sm...

👉 https://www.jrpanel.com/T 👈 Engineers who are just getting started or just entering the electronic design position, may don't know how to construct a good PCB, or even what the layers are, how to define and distinguish when they get a board. Next, we will take you to uncover the veil of PCB and explain each layer in detail. Layer Description Top Layer Mainly used to place components , and can be used for wiring for laminates and multilayer boards Mid Layer There can be up to 30 layers, which are used to route signal lines in multilayer boards Bootom Layer Mainly used for wiring and welding, sometimes components can also be placed Top Over layer Used to mark the projection outline of the component, the label, nominal value or model of the component, and various annotation characters Bottom Over layer It has the same function as the top silk screen layer, if all kinds of labels are contained in the top silk screen layer, then the bottom silk scr...

👉https://www.jrpanel.com/T👈 The membrane switch is a new type of switch device that needs to touch the panel on the switch to complete the on and off of the controlled circuit, replacing the key form of the mechanical switch. Then what are the benefits of membrane switch in lamps and lanterns?   Convenient installation : No need to connect the neutral wire, no need to change the used lamps , and the original wall switch can be directly replaced.   Applicable lamps and lanterns : the membrane switch can be connected to fluorescent lamps, energy-saving lamps, incandescent lamps, spotlights, halogen lamps and other common lamps.   Lightning protection : The membrane switch is equipped with lightning protection function, so it is safe and reliable.   Partition wall remote control : The membrane switch can remotely control through the wall.   No interference with each other : The membrane switch adopts digital coding and decoding technology, whi...

👉 https://www.jrpanel.com/T 👈 Circuit layer printing is the most important factor reflecting the inherent quality of membrane switches. Circuit should be restricted by parameters such as current, resistance, withstand voltage, insulation, and life span. This is also a concrete manifestation of the penetration of screen-printed products into functional and high-tech fields. To ensure the function of the circuit, the screen of the printed circuit should be guaranteed first. Combining the requirements of the circuit parameters and the requirements of the structural elements in the circuit for screen printing are described below.   (1) The resistance of a wire made of the same thick conductor is inversely proportional to the cross-sectional area of the wire; the current passed is proportional to the cross-sectional area; its contact abrasion resistance is proportional to the thickness of the contact. It can be seen that the thickness of the circuit pattern printed by the me...

👉https://www.jrpanel.com/T👈 Nowadays, medical electronics has entered our lives. It is no longer just to see smart medical devices in hospitals. Small wearable devices have been put in our pockets. Personal health monitoring devices such as blood pressure meters and blood glucose meters have won everyone’s attention.  With the continuous development of medical electronics, the requirements in terms of power consumption, performance, and price have increased, which has become a new round of challenges for medical electronic equipment. Reasonable solutions can meet people's needs and market development. Reduce power consumption to achieve tiny, intelligent  power management In terms of  circuit  principle, it is necessary to build a portable medical device that requires low power consumption and a wide voltage operating range, so as to achieve a simplified design and a small size system power management design.  In order to meet more functions of the system, fro...

👉 https://www.jrpanel.com/T 👈 According to the switch principle, touch switches are divided into resistive touch switches and capacitive touch switches.  Among various technologies, capacitive touch sensing technology has become the mainstream of touch sensing technology. In the keystroke scheme, it can improve the overall appearance of the product.  What is a capacitive sensor touch switch? JRPanel  membrane switch  manufacturer shares: The capacitive sensor touch switch can penetrate 20 mm of the insulating material shell (glass, plastic, etc.) to accurately detect the effective contact of the finger to ensure that the sensitivity, stability, and reliability of the product will not be affected by changes in environmental conditions or long-term use Changed, with strong waterproof and anti-interference ability.  It is understood that there are many types of multi-touch technology, but the following four are relatively mature: 1. "LLP Technology" mainly uses i...

👉 https://www.jrpanel.com/T 👈 Medical equipment and devices must be designed with rigorous standards to function in environments where patient safety and product reliability are critical. Today, there is great demand for innovative, feature-rich, and affordable electronic equipment to be used in diagnostic labs, hospitals, and clinics, as well as for consumer self-care. Engineers are constantly challenged to deploy differentiating leading-edge electronics that demonstrably improve patient care in a cost-effective manner for in-home patient care and portable monitoring and therapeutic devices. Mechanical membrane switches and increasingly feature-rich capacitive user interfaces are used in a wide range of medical equipment and devices — defibrillators, EKG leads, electronic sensors, glucose meters, infusion pumps, patient monitors, and portable oxygen units, as well as disposable dental, medical, and surgical equipment. Therefore, it is important to closely compare and understand the ...
