Described heating control apparatus: by being installed at the bottom of the case or base upper heater, temperature sensor and the control circuit of etching working portion constitute.According to the temperature value of setting, control heater improves etching speed to liquid heat in certain temperature range.
Advantage of the present invention and remarkable result:
The present invention is simple in structure, and is easy and simple to handle, makes fast, and processing cost is low, is fit to school student Electronic Design innovative experiment and uses.Student just can process a single face circuit board several to tens minutes.Can process simultaneously the polylith circuit board is several student's services.The correct also correct of the very fast proof scheme design of student is made again.The present invention is a good teaching equipment of cultivating electrical type Major innovation ability, also can be used as breadboard experimental facilities and uses.
Description of drawings
Fig. 1, one-piece construction synoptic diagram of the present invention.
Embodiment
Describe below in conjunction with accompanying drawing.
Shown in Figure 1, temperature control cycling circuit plate etching and processing device of the present invention.It comprises casing 1, etching working portion 2, fluid circulation system, heating control apparatus 3, electric control system 4; Described etching working portion is loaded in the casing;
The l casing is the corrosion resistant plastic box of a upper opening.
L etching working portion 2; Comprise base 2-1, liquid flow chamfered portion 2-2; Described base is made up of base plate and the welding of front and back side plate, and wherein: the front and back side plate was last to be provided with several logical liquid and the through hole of wearing electric wire, and at base plate and front side board place an armored pump case is set; Described liquid flow chamfered portion is welded on the described base; Front end at described liquid flow chamfered portion is provided with a microscler liquid tank 2-3 with dividing plate.In order to prevent that liquid from spraying in the process of pump, in liquid tank 2-3, install an inverted v-shaped baffle plate 2-4 additional.
The l fluid circulation system is made up of the casing of liquid storage, pump 5, liquid tank 2-3 and the liquid flow inclined plane part branch that is contained in the armored pump case; Wherein: on the feed tube of pump was arranged at the bottom of the base of etching working portion, the drain pipe of pump was communicated with liquid tank 2-3; Liquid is extracted out from the casing of liquid storage by pump, evenly flows out through liquid tank 2-3 limit, and liquid flows to bottom half through the inclined-plane of liquid flow chamfered portion 2-2, is smoked by pump to form liquid and recycle again.
