Background technology
PCB, Chinese is printed circuit board, also known as printed-wiring board (PWB), is the supporter of electronic devices and components, is the carrier of electronic devices and components electrical connection.Because it adopts electron printing to make.Etch process is the basic production step making pcb board.Etching utilizes etching solution not removed by the copper of resist cover part, generates the conducting wire needed.
In etching process, pcb board time in etching solution is longer, and lateral erosion is more serious.Lateral erosion has a strong impact on printed conductor precision, and serious lateral erosion will make making fine wire become impossible, and lateral erosion excessively can cause wire break.Immersion type etching can cause larger side to lose, and it is less, especially best with spray etching effect that spilling and spray-type etch lateral erosion.
Spray etching often adopts lateral etch processing procedure production line, and lateral etch processing procedure many employings horizontal roller drives pcb board, utilizes nozzle on jet arrays to pcb board surface sprinkling etching solution.But this etching mode inevitably forms puddle effect, namely the etching efficiency of pcb board central ministries and agencies is lower than edge section etching efficiency, and the etching solution of edge easily flows away, thus the etching solution renewal speed of pcb board edge section is fast, etching speed is also fast, is therefore formed in one " puddle " at central part.In addition, lateral etch can only etch the front of pcb board, and cannot etch reverse side, etching efficiency is lower.
