Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] see figure 1 and figure 2 As shown, the invention provides a measurement board for the horizontal ultrasonic intensity of a circuit board, including a board body 1 and tinfoil paper 2, the board body 1 is provided with an opening 3, and the tinfoil paper 2 is sealed on the opening. Paste the tin foil paper 2 on the opening 3 with the surface glue, and stick it tightly around without gaps. The thickness of the tin foil paper 2 is 10 μm, 15 μm or 20 μm; the size of the board body 1 is made according to the inner diameter of the ultrasonic section of the horizontal line , so that the plate b...

Abstract

The invention relates to a measurement plate and a measurement method for measuring circuit board horizontal line ultrasonic intensity, comprising a plate body and tin foil paper; the plate body is provided with an opening which is sealed by the tin foil; and the thickness of the tin foil paper is 10-20 Mum. The measurement method for measuring circuit board horizontal line ultrasonic intensity comprises steps of transmitting the measurement plate having a first preset thickness to a ultrasound wave band, enabling the tin foil paper to vibrate in the ultrasonic wave to test that whether the tin foil paper is damaged by the measurement plate which stops for a first time frame in the ultrasonic wave band, transmitting a measurement plate having a second preset thickness to the ultrasonic wave band, enabling the tin foil paper to vibrate in the ultrasonic wave in order to test whether the tin foil is damaged by the measurement plate which stops for a second preset time frame in the ultrasonic wave band, and determining whether the ultrasonic wave band intensity is in the first intensity range according to the fact whether the tin foil paper having the first preset thickness and the second preset thickness is damaged.

Description

technical field [0001] The invention relates to the field of printed circuit board production, and in particular designs the ultrasonic intensity measurement of the horizontal line containing the ultrasonic water washing section in the production process of the printed circuit board. Background technique [0002] In the process of circuit board production, there are many processes that require ultrasonic cleaning, for example, the washing section of the outer layer pretreatment, the washing section of the solder mask pretreatment and the washing of the finished board, etc., using ultrasonic cleaning can effectively remove oil and impurities on the board surface . [0003] During the equipment maintenance process, it is necessary to maintain and measure the ultrasonic cleaning section to ensure the strength and stability of the ultrasonic waves. [0004] To measure the ultrasonic intensity in the prior art, an instrument for measuring the ultrasonic intensity is required, bu...
