Who is the noble PCB color secret Many DIY players will find that the PCB colors used by various board products in the market are varied and dazzling. The more common PCB colors are black, green, blue, yellow, purple, red, and brown. Some manufacturers also developed PCBs with different [...]

PCB micro-slice resin selection benchmark 1, low peak temperature If the peak temperature is too high, it will cause oxidation of copper and affect the observation of the slice under the microscope. When the powder is mixed, it will generate heat. If the temperature is too high, the viscosity [...]

Having a rich knowledge base of a pad is essential for a good PCB engineer. Many people will draw pad according to the component manual, but when drawing, pay attention to how to draw the best pad. I believe these tips Will make you learn more about the more [...]

Is the PCB copper wire off? You may have to pay attention to these three points The copper wire of the PCB is detached (also often referred to as beryllium copper). The PCB factory said that it is a laminate problem and requires its production plant to bear bad [...]

First, the reason for laying copper:   EMC, for large areas of ground or power supply copper, will play a shielding role, some special, such as PGND play a protective role.   PCB process requirements, generally in order to ensure the plating effect, or laminate is not deformed, for [...]

PCB circuit board layer full resolution The bottom pad layer of the top layer of the PCB circuit board: Toppaste and Bottompaste are the bottom pad layer of the top layer. It refers to the exposed copper we can see. (For example, we drew a wire in the top [...]

Harwin has further expanded its Sycamore Contact product, which initially covered only 1 and 1.5 mm diameter wire pins, but now covers 0.80 to 1.90 mm lead sizes.   In many cases, electronic devices/modules need to be replaced over time (eg, depleted gas sensors or bad energy harvesting sensors, [...]

Some Feasible Processes for Manufacturing PCBs First, the line Minimum line width: 6mil (0.153mm). In other words, if the line width is less than 6 mil, the line width will not be able to be produced. (The minimum width of the inner layer width of the multilayer board is [...]

Copper board production process Copper is an abbreviation for Eletcroless Plating Copper, also known as Plated Through Hole (PTH), which is an autocatalytic redox reaction. After two or more layers are drilled, the PTH process is performed. The role of PTH: A thin layer of chemical copper is chemically [...]
