What is PCB circuit board? According to the dictionary of technical tems, this abbreviation means Printed Circuit Board. It can be found a self-contained module of interconnected electronic components found in all even the simplest electronic devices such as beepers, pagers, radios and even sophisticated radar and computer systems. The main task of PCB circuit board is to mechanically support and electrically connect electronic components using conductive tracks or pads.

PCB circuit board is the cornerstone of the electronics industry, and the circuit of all electronics requires PCB circuit board. PCB industry has been very mature, with limited growth rate or decline margin. In 2008 and 2009, the output value of PCB industry decreased due to the fierce price competition. In 2010, the electronics industry rebounded, but PCB industry only grew by 10.5%. In 2011, the growth rate of PCB industry is expected to be merely 5.1%.

The internal PCB circuit board of ordinary mobile phones employs the design of 1HDI+2 traditional boards +1HDI, with HDI as the outer layer and the traditional board as the inner layer.
Intermediate and high-end smart phones adopt the design of 2 +2 +2 and 3 +2 +3, with 4 layers and 6 layers of HDI PCB used respectively. In addition, iPad1 uses 1HDI +8 boards (traditional) +1 HDI, with 2 layers of HDI. iPad2 renders 3 +4 +3, with 6 layers of HDI, namely Any-Layer HDI PCB, which reduces the thickness to be 0.88 cm. The thickness of iPad1 is 1.34 cm.
New type of iPad is 1/3 thinner than old type,mainly because HDI PCB ︱High density PCB︱High Density Interconnect PCB circuit board develops from the original multi-layer board to Any-Layer HDI PCB, and Any-Layer has dense holes. Nevertheless, the hole diameter of Any-Layer must be done by laser drilling instead of machine drilling. In the future, iPhone 5 will be lighter and thinner like iPad 2.
