Aluminum pcb vs fr4 pcb board

FR4 board is a code name for the grade of flame-retardant material. It represents a material specification that the resin material must be able to extinguish by itself after burning. It is not a material name, but a material grade. Therefore, there are many types of FR-4 grade materials used for pcb, but most of them are composite materials made of so-called Tera-Function epoxy resin, Filler and glass fiber.

FR-4 PCB board, according to different uses, industry insider generally call them: FR-4 Epoxy Glass Cloth, insulating board, epoxy board, epoxy resin board, brominated epoxy resin board, FR-4 , Fiberglass board, fiberglass board, FR-4 reinforcement board, FPC reinforcement board, flexible circuit board reinforcement board, FR-4 epoxy resin board, flame-retardant insulation board, FR-4 laminated board, epoxy board , FR-4 light board, FR-4 fiberglass board, epoxy glass cloth board, epoxy glass cloth laminate, circuit board drilling pad etc.

Main technical features and applications of FR-4 board: stable electrical insulation performance, good flatness, smooth surface, no pits, thickness tolerance standards, suitable for high-performance electronic insulation requirements products, such as FPC reinforcement board, PCB drilling pad, glass fiber meson, potentiometer carbon film printed glass fiber board, precision star gear (wafer grinding), precision test plate, electrical (electrical) equipment insulation support spacer, insulation backing plate, transformer insulation plate, motor insulation, grinding gear, electronic switch insulation board, etc.

The aluminum pcb board is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single-sided aluminum PCB is composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. For high-end use, it is also designed as a double-sided board, and the structure is circuit layer, insulating layer, aluminum base, insulating layer, and circuit layer. Very few applications are multi-layer boards, which can be formed by bonding ordinary multi-layer boards with insulating layers and aluminum bases.

How to solder the flexible PCB board?

  Before soldering, apply flux to the pad and treat it with a soldering iron to avoid poor tin plating or oxidation of the pad, resulting in poor soldering. Generally, the chip does not need to be processed. Use tweezers to carefully place the PQFP chip on the PCB board, taking care not to damage the pins. Make it aligned with the pad and ensure that the chip is placed in the correct direction. Adjust the temperature of the soldering iron to more than 300 degrees Celsius, dip a small amount of solder on the tip of the soldering iron, press down the aligned chip with a tool, and add a small amount of solder to the two diagonal pins. Hold down the chip and solder the pins on the two diagonal positions to make the chip fixed and unable to move. After soldering the opposite corners, recheck the alignment of the chip position. If necessary, adjust or remove and realign the position on the PCB board. When starting to solder all the pins, add solder to the tip of the soldering iron, and a...

How is the cost of SMT patch soldering calculated

The calculation of SMT patching prices is now almost transparent, and the algorithm for determining the cost per point is straightforward. However, it is first necessary to clarify the concept of "point". Different companies adopt varying algorithms, but for a PCB board, the total cost of SMT patching processing remains consistent. The core of SMT patching processing is to mount surface - mount components onto the solder pads of a PCB. Some companies count one solder pad as one point, while others consider two solder pads as one point. In this article, we take the example of calculating one point per solder pad. It only requires calculating all the solder pads on the PCB board. However, for some special components such as inductors, large capacitors, ICs, etc., additional calculations are needed. The specific empirical methods are as follows: for example, an inductor can be counted as 10 points, and an IC is calculated as half the number of pins (for example, a 40 - pin IC is...

How can we identify Integrated Circuits board and PCBA

  Inspect the surface of the PCB component body If a used  circuits board   part has been polished to make it look new, there may be tiny scratch patterns on the surface when observed under a magnifier. If it is covered up with paint on the surface, it will look bright and have no plastic texture. Inspect the printed text High-quality producers use laser printers to print the text silk-screen. It has a clear appearance, is non-conspicuous, and is difficult to erase. Typically, the text on refurbished chips is printed fuzzy and is not as sharp. You may find that the edges of the characters are blurred. The characters may be offset and the shades and colors may not be uniform. Moreover, many re-furbished chips use stencils for re-printing. In this case, if you feel the printed text, it should be easy to tell if it is new or refurbished. Inspect component pins If the component pins are shiny with a thin coating, then it may be refurbished. Original components are tin plated,...
