Solderless prevention device when soldering chip on printed circuit board automatically

摘要

One The technical field of the invention recorded within the scope of the request;The invention forms the gas generated when the automatic welding is fair on the engine printed circuit board of the chip, and the gas hole is formed in the chip, so as to avoid the engine defect of the chip.;Two Technical issues to be solved in invention;In order to prevent the occurrence of automatic welding part, gas holes are respectively formed between the pattern sections formed on the printed circuit board, and the printed circuit board with automatic welding is provided on the printed circuit board.;Three The solution of the invention is important;The invention relates to a printed circuit board (1) whose image (2) is a conductive circuit (5) and a printed circuit board of the chip (4) when the shortened chip (4) is used as the abbreviationOn the left and right sides of the grid, they are separated by a distance to form the opposite direction,In chess Park (2), the gas of chemical gas generated during automatic welding is formed respectively.;Four Important uses of the invention;The invention prevents the automatic welding part on the printed circuit board from the pattern up and down formed on the printed circuit board,The gas hole is formed between the left and right parks. When automatic welding is carried out, the elastic gas of chemicals is discharged through the gas cylinder. The engine of printed circuit belt and chip will not improve the welding quality due to non payment.In addition, it is not necessary for the staff to retrieve the effect of welding of the unpaid part.
