Circuit board surface cleaning device

Abstract

A circuit board surface cleaning device is provided for cleaning a surface of a circuit board placed on a carrier during a manufacturing process of the circuit board. The circuit board surface cleaning device includes a pipe having an air outlet and mounted on the carrier, and at least one airflow pipeline connected to one end of the pipe, allowing air from the airflow pipeline to be output through the air outlet to the surface of the circuit board so as to remove contaminants on the surface of the circuit board, which can increase the quality of the circuit board and reduce damage to the manufacturing equipment for the circuit board.

1 . A circuit board surface cleaning device for cleaning a surface of a circuit board on a carrier during manufacture of the circuit board, the circuit board surface cleaning device comprising: 
 a pipe mounted on the carrier and having an air outlet; and    at least one airflow pipeline connected to one end of the pipe, allowing air from the airflow pipeline to flow through the air outlet of the pipe to the surface of the circuit board to remove contaminants on the surface of the circuit board.    
   
   
       2 . The circuit board surface cleaning device of  claim 1 , further comprising at least one supporting member for fixing the pipe on the carrier.  
   
   
       3 . The circuit board surface cleaning device of  claim 2 , wherein the supporting member comprises a supporting base mounted to the carrier, and a sliding part capable of sliding in relation to the supporting base and for adjusting a position of the pipe.  
   
   
       4 . The circuit board surface cleaning device of  claim 3 , wherein the supporting base has at least one sliding groove attached to the sliding part via at least one fixing part that penetrates the sliding groove, so as to set a position of the sliding part and a height of the pipe.  
   
   
       5 . The circuit board surface cleaning device of  claim 4 , wherein the sliding part is formed with a through hole for accommodating the pipe, and at least one positioning hole for accommodating the fixing part.  
   
   
       6 . The circuit board surface cleaning device of  claim 5 , wherein the fixing part is a bolt and the positioning hole is a threaded hole.  
   
   
       7 . The circuit board surface cleaning device of  claim 5 , wherein the sliding part further includes a screw penetrating a side thereof to reach the through hole and press the pipe so as to hold the pipe in position and set a predetermined direction of the air output from the air outlet.  
   
   
       8 . The circuit board surface cleaning device of  claim 1 , further comprising an air pressure source connected to the airflow pipeline.  
   
   
       9 . The circuit board surface cleaning device of  claim 8 , wherein the air pressure source is an air pump.  
   
   
       10 . The circuit board surface cleaning device of  claim 8 , wherein the air pressure source includes an on/off control valve for controlling the air pressure source.  
   
   
       11 . The circuit board surface cleaning device of  claim 10 , wherein the air pressure source further includes an airflow control valve for controlling an amount of flow of the air.  
   
   
       12 . The circuit board surface cleaning device of  claim 1 , wherein the air outlet comprises one of a plurality of holes and a plurality of slots.  
   
   
       13 . The circuit board surface cleaning device of  claim 1 , wherein the air outlet is a long slot.  
   
   
       14 . The circuit board surface cleaning device of  claim 1 , further comprising a curve tube for connecting the pipe to the airflow pipeline.
