    The chip size is usually 1 mm 1 mm while the module is usually about 10 mm 10 mm. Due to the high power requirement many modules are then attached to the printed circuit board (PCB) substrate which is further bonded with a large heat sink. The sizes of the typical LED lamp change from several centimeters to meters. The printed circuit board (PCB) manufacturing process requires a complex procedure to ensure the performance of the finished product. Though circuit boards can be single double or multilayered the fabrication processes used only differ after the first layer s production.

  • What Is PCB(Printed Circuit Board) PCB Basics

    Printed circuit board also known as PCB is the electrical connection provider of the electronic components. It has been developed for more than 100 years its key point is about layout design. The main advantage of using circuit board is to greatly reduce wiring and assembly errors improve the level of automation and productivity. Surface-mount technology (SMT) is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). An electrical component mounted in this manner is referred to as a surface-mount device (SMD) industry this approach has largely replaced the through-hole technology construction method of fitting components in large part because SMT allows
