For the rust removal of copper stamping parts, the commonly used copper rust removal process is the chemical treatment process. The specific methods are as follows:If there is only a little rust and oil on the copper stamping parts, the following treatment process can be used: copper material rust r

As hardware terminals in electronic products, their precision and requirements are crucial in electronic products.Selection and differentiation of materials for hardware terminal p

Common hardware surface treatment methodsHardware surface treatment refers to the process of giving the surface of hardware products beautiful and anti-corrosion effects through a series of processing techniques. The following are several common hardware surface treatment methods:PlatingPlating is o

Common factors affecting the speed and quality of galvanizing.In the actual production process, the common factors affecting the speed and quality of galvanizing are:(1) Incomplete pretreatmentThere is an oxide film on the surface of the workpiece, which affects the normal deposition of zinc.(2) Poo

Solution to the problem of punching size of metal stamping parts not meeting the requirementsDuring the production process of metal stamping parts, the punching size may be too large or too small, and there may be a large difference with the punch size. In order to solve such problems, in addition t

Causes of burrs on stamped parts1. Stamping process problemsIrrational stamping process is an important cause of burrs. Specifically, too fast stamping speed, insufficient stamping depth, and too large stamping die gap may cause burr problems. These problems may cause the metal material to fail to c

Causes of burrs on stamped parts1. Stamping process problemsIrrational stamping process is an important cause of burrs. Specifically, too fast stamping speed, insufficient stamping depth, and too large gap between stamping dies may cause burrs. These problems may cause the metal material to fail to

The main function of the patch terminalProtect the thin chemical copper just deposited to prevent it from being etched by acid, and thicken it to a certain extent through electroplating. Provide sufficient conductivity, thickness and prevent heating and mechanical defects in the conductive circuit.P

Materials used for shielding coversShielding covers are mainly designed to prevent electromagnetic interference and can shield components and LCM on PCBs.The widely used ones on the market are: fixed shielding covers (directly welded to the PCB with SMT), and removable shielding covers (combined wit

Main features of stamping partsStamping parts are mainly non-metallic sheets or metals, which are stamped by developed stamping dies and formed by the pressure of presses.The main features of stamping parts are as follows:1. Stamping parts are made by stamping under the premise that material consump
