Advantages&Disadvantages of aluminum PCB printed circuit boards

 

  1. It is more suitable for SMT process;
  2. Meet the requirements of RoHs;
  3. The heat dissipation has been effectively treated, thereby reducing the operating temperature of the module, prolonging the service life and improving the reliability;
  4. The volume is decreasing, reducing the assembly area of ​​radiators and other hardware, reducing product volume, and reducing hardware and assembly costs;
  5. Good mechanical durability, better than ceramic circuit boards made by some simple processes.

Disadvantages of aluminum pcb printed circuit boards

  1. Higher cost: Compared with other cheap PCB products, the price of aluminum-based PCB boards accounts for 30% of the total product price.
  2. At present, the mainstream manufacturer can only make single-sided PCB boards, and it is difficult to make double-sided aluminum PCB boards. At present, single-sided aluminum PCB boards are relatively skilled in China, and the process and technology of multi-layer aluminum PCB boards are relatively mature in foreign countries. Good news is, through years of aluminum pcb board designing and manufacturing, Hitech are able to provide high quality and cost effective single layer, double layer and multi layer aluminum pcb boards.
  3. The thermal conductivity test method and the test result do not match, the thermal conductivity of the dielectric layer and the thermal conductivity of the aluminum-based PCB board are different to a certain extent.
  4. The material standards for aluminum-based copper-clad PCB boards are not unified. There are CPCA industry standards, national standards, international standards, etc.
  5. If the thickness of the copper foil does not meet the standard, it will cause some phenomena such as burning the circuit and exploding the power supply. However, we never occur such problems.

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,...
