Problems solved by technology

However, when the amount of solder paste is too large, the scraper 2 still cannot avoid solder paste remaining on the outside of the scraper, and the solder paste accumulates on the working platform for a long time and hardens
[0007] Therefore, how to solve the problems in the prior art that the solder paste remains on the outside of the scraper and the solder paste accumulates on the working platform for a long time and hardens has become a problem to be solved at present.

Abstract

The invention discloses a scraper. The scraper is characterized in that second scraper blades are respectively arranged on two opposite sides of a first scraper blade. When the scraper executes the solder paste scraping action on a worktable of the solder paste coating machine, solder paste overflowing out of two sides of the first scraper blade is toggled into the inner side of the first scraper blade by the second scraper blades, so that the solder paste can be prevented from being resided on the outer side of the first scraper blade and further the phenomenon that the solder paste is hardened due to long-time accommodation on the worktable is avoided. In addition, the invention also discloses a solder paste coating machine with the scraper and a scraping method.

Description

[0001] technical field [0002] The invention relates to a scraper, in particular to a scraper which can prevent solder paste from remaining on the outside of the scraper during scraping off the solder paste. Background technique [0003] Surface mount technology or surface mount technology (Surface Mount Technology; SMT for short) is mainly an assembly technology used in electronic products. The assembly method is to first apply solder paste to the printed circuit board (Printed Circuit Board; PCB), and then solder the surface-mounted electronic components, such as resistors, capacitors, transistors and / or integrated circuits (Integrated Circuit; IC for short), on the printed circuit board. [0004] In the existing solder paste coating technology, such as Figure 1A As shown, it first places a screen 10 on the working platform 90 of a solder paste coating machine 9, then places the circuit board (not shown) under the screen 10, and then coats the solder paste 11 on the scre...
