Problems solved by technology

[0002] The printed board will generate instantaneous high temperature when drilling, and the epoxy glass substrate is a poor conductor. When drilling, the heat is highly accumulated, and the surface temperature of the hole wall exceeds the glass transition temperature of the epoxy resin. As a result, the epoxy resin along the hole wall The surface flows to produce a thin layer of slag. If the slag is not removed, the signal connection in the multi-layer board will not be smooth, or the connection will be unreliable; Clean up.

Embodiment Construction

[0053] Please refer to Figure 1 to Figure 7 As shown, it shows the specific structure of the embodiment of the present invention, including filter membrane module 10, filter pump 20, cleaning bucket 30, cleaning pump 40, liquid inlet, sewage outlet, water production port, compressed air port and tap water mouth.

[0054] Wherein: the filter membrane module 10 is built with multiple sets of filter membranes (not shown in the figure), and the filter membrane module 10 has a water inlet 11, a water outlet 12 and an air inlet 13;

[0055] The water inlet 11 of the filter membrane module 10 communicates with the outlet of the filter pump 20 through the first pipeline ①, the inlet of the filter pump 20 communicates with the second pipeline ② one end, the second pipeline ② communicates with the liquid inlet, and the first A pipeline ① is provided with a water inlet valve BV01. The waste water flows into the filter membrane module 10 through the liquid inlet, the second pipeline ②,...

Abstract

The invention discloses PCB smear removal drug liquid filtration recycling equipment and a smear removal drug liquid filtration recycling method thereof. The equipment comprises a filtration film assembly, a filtration pump, a washing barrel, a washing pump, a liquid inlet, a sewage draining outlet, a water production port, an air compressed port and a running water port. Automated filtration andsmear removal are achieved through arrangement and mutual cooperation of the components. Automated washing is achieved mainly through arrangement and mutual cooperation of the filtration film assembly, the filtration pump, the washing barrel, the washing pump and valves. Washing is performed through circulation washing by adopting a drug preparation, and running water washing effectively guarantees smear stuck to the filtration assembly is removed clearly. In this way, the filtration film assembly can achieve the effect of repeated cyclic using without being replaced, and the replacement costis saved.

Description

technical field [0001] The invention relates to the technology in the field of PCB processing, in particular to a device for filtering and recycling PCB desmearing liquid and a method for filtering and recycling the liquid. Background technique [0002] The printed board will generate instantaneous high temperature when drilling, and the epoxy glass substrate is a poor conductor. When drilling, the heat is highly accumulated, and the surface temperature of the hole wall exceeds the glass transition temperature of the epoxy resin. As a result, the epoxy resin along the hole wall The surface flows to produce a thin layer of slag. If the slag is not removed, the signal connection in the multi-layer board will not be smooth, or the connection will be unreliable; Clean up. At present, PCB scum is removed by soaking and rinsing with chemical agents to remove printed board slag, and the chemical agent has strong oxidative properties and is expensive; in terms of my country's increase...
