Circuit boards are very common, our home appliances are equipped with circuit boards, in order to ensure the quality of the welding, business owners will be on the solder joints of the false solder, leakage of solder detection is placed on an important position. Detection methods in addition to the traditional visual inspection, more and more circuit board factory will use the flaw detection machine to do the inspection. Circuit board common defects are many, in the process of processing there will be a number of factors will affect its quality. Common factors are:
 
1. PCB circuit board board surface contamination will have an impact on the solderability, these defects include tin beads, tin balls, open circuit, bad gloss, etc., which will directly affect the quality of BGA soldering.
 
2. The drilling process is not qualified to lead to poor solderability of the board hole, resulting in poor contact between the components and part of the line after welding.
 
3. Board warpage is too large is also an important cause of false soldering.
 
4. the rationality of the layout of electronic components and heat dissipation will also affect the quality of soldering. Once the bad, the board will be scrapped, mature enterprises which will use the flaw detection machine to detect. Flaw detector machine has access to the production line, with efficient detection, clear positioning, large detection area, strong resolution, high magnification characteristics, can help business owners better control the quality of the circuit board.
 
In view of the powerful nature of the flaw detector, it can be widely used in IGBT semiconductor inspection, BGA chip inspection, LED strip inspection, PCB bare board inspection, lithium battery inspection, aluminum casting nondestructive flaw detection and so on.
