In the PCB industry, the English word PCBA often appears. As people in the industry, we are already familiar with this word. But many novices often confuse PCBA with PCB board printer and still don't know that these two words actually have different meanings. Today, we will talk about the difference between PCBA and PCB.
PCB is the abbreviation of Printed Circuit Board, which is PCB board printer. Due to it is made by printing, it is called "printed" circuit board. PCB is an important electronic component in electronic equipment, a support for electronic components, and a carrier for electrical connection of electronic components. PCB printing plates have been extremely widely used in the production of electronic products and are known as the "mother of electronic components".
PCBA is the abbreviation of Printed Circuit Board and Assembly, which means that PCBA passes through the entire process of blank printed circuit board SMT loading and then DIP plug-in.
Here, SMT and DIP are both ways to integrate parts on the PCB printed board. The main difference is that SMT does not need to drill holes on the PCB. In DIP, the PIN pins of the parts need to be inserted into the drilled holes.
SMT refers to surface mount technology, which mainly uses mounters to mount some tiny parts on PCB board printer. The production process is: PCB board positioning-printing solder paste-placement machine placement-through the reflow oven-finished inspection.
DIP stands for "plug-in", that is, inserting parts on the PCB board. For integrated parts that are large in size and not suitable for placement technology, this type of plug-in form is required. The main production process is: sticking adhesive-plug in-inspection-wave soldering-brushing-inspection finished.
