Embodiment
Describe the present invention for the ease of it will be appreciated by those skilled in the art that below in conjunction with embodiment and accompanying drawing:
Shown in accompanying drawing 1,2,3,4, the scheme that present embodiment disclosed relates to a kind of testing circuit plate ion pollution detection device.
This device comprises the mainframe 1 that an aluminium section bar is spliced to form, and at mainframe 1 upper surface marble panel 18 corrosion-resistant, that be convenient to clean is installed.Below marble panel 18, be fixed with rinse bath 11, be contained with extract in the rinse bath 11.This rinse bath 11 is a flat, setting is fixed in the mainframe 1, and this shape just circuit board shape with to be detected is consistent, can only need less extract can soak circuit board fully, certainly, have on marble panel 18 surfaces and be convenient to the opening that circuit board picks and places.
Be provided with the electrothermal tube 9 that extract is heated in rinse bath 11 bottoms.The water delivering orifice of rinse bath 11 also is positioned at rinse bath 11 bottoms, and water inlet is positioned at the sidewall of rinse bath 11, is communicated with by circulation main pipe rail 12 between water delivering orifice and the water inlet.And, also be disposed with detecting electrode 21, cooling bend pipe 15 and the ion exchange column 3 of valve 4, pump 5, conductivity meter 2 in the circulation main pipe rail 12 between water delivering orifice and water inlet.Valve 4 is used to control the break-make of whole circulation main pipe rail 12.Pump 5 provides power for extract flows.Detecting electrode 21 is used to detect effects of ion content and shows and print by conductivity meter 2.Cooling bend pipe 15 is used to reduce the temperature of extract, in order to quicken cooling, also is provided with radiator fan 10 on the next door of cooling bend pipe 15.Ion exchange column 3 does not need to pass through from these parts owing to contain the extract of ion when detecting ion concentration, so be provided with normally closed solenoid valve 7 at these parts two ends for extract being carried out the extract remanufactured component of ion cleaning.Therefore, in circulation main pipe rail 12, also be provided with a branch road 6 in parallel, also be provided with a normally open solenoid valve 8 in this branch road 6 with ion exchange column 3 and normally closed solenoid valve 7.
The ion on the circuit board incorporates in the extract fast in the extract in order to quicken to immerse, and the water inlet of rinse bath 11 is provided with 3 shunt parallel with one another 13, and each is arranged up and down along separate routes, and is provided with the control valve 14 of regulating flow.When the high speed extract enters in the rinse bath 11 from shunt 13, in rinse bath 11, form convection current, quickened the dissolving of extract greatly to ion on the circuit board, improved whole detection speed.Certainly, 13 quantity also is not limited only to 3 along separate routes, also can be 2,4 even 5.
Each above-mentioned valve, pump 5 and conductivity meter 2, ion exchange column 3 all connect control by control circuit, realize co-ordination, and the control panel of control circuit is installed on marble panel 18 surfaces.
When normal the detection, at first circuit board under test is put into rinse bath 11, and submergence fully, open control circuit then, pump 5, conductivity meter 2 all begin action, and extract begins circulation in global cycle pipeline 12, ion on the circuit board enters in the extract, when extract during through the detecting electrode 21 of conductivity meter 2, detecting electrode 21 can detect the extract ions content, shows by conductivity meter 2 and prints.
After detection is finished, need clear up regeneration to the extract intermediate ion, to close normally open solenoid valve 8, open the normally closed solenoid valve 7 at ion exchange column 3 two ends, extract is by ion exchange column 3, and the ion in the extract is cleaned out, and extract regeneration is finished.
Whole device is after using repeatedly, and needs are changed extract and circulation main pipe rail 12, each parts are cleaned, and also are provided with blow-off line 16 in circulation main pipe rail 12 bottoms, and blow-off line 16 both sides are provided with sewage draining valve 17.When needs discharge inner waste liquid, only need open sewage draining valve 17, waste liquid then can be discharged voluntarily.
Whole device appearance is succinct, and can in mainframe 1 bottom pulley 19 be installed so that move, specifically referring to shown in the accompanying drawing 5.
Following table and accompanying drawing 6 respectively detect data and curve when being embodiment of the invention actual detected circuit board,
From last table and accompanying drawing 6 as can be seen, NaCl total ion concentration of equal value is 0.14 μ g Eq NaCl/Sqcm in the extract, less than ionic soil standard-required 0.15 μ g Eq NaCl/Sqcm value, proves that the circuit board ion of this detection is being paid the requirement of amount conformance with standard.Simultaneously as can be seen, when area of detection is the circuit board of 4200.0Sqcm (square centimeter), promptly reached the balance of conductivity and NaCl total ion concentration of equal value detection in 2 minutes, the speed of detection and precision are all very high.
Following table and accompanying drawing 7 respectively detect data and curve when being present embodiment actual detected circuit board,
From last table and accompanying drawing 7 as can be seen, NaCl total ion concentration of equal value is 0.29 μ g Eq NaCl/Sqcm in the extract, obviously, prove that the circuit board ion amount of paying of this detection does not meet standard-required greater than ionic soil standard-required 0.15 μ g Eq NaCl/Sqcm value.Equally as can be seen, when area of detection is the circuit board of 4200.0Sqcm (square centimeter), also only need promptly to have reached in 2 minutes the balance of conductivity and NaCl total ion concentration of equal value detection, the speed of detection and precision are all very high.
From such scheme as can be known, no matter the present invention, possesses the creative requirement of patent of invention from technical scheme or technique effect all has substantive distinguishing features and obvious improvement.
Present embodiment need to prove for one of preferable implementation of the present invention, and any conspicuous replacement all belongs to the infringement trip and is all within protection domain of the present invention under the prerequisite that does not break away from the present invention's design.
