Abstract
The invention provides a method for processing the pore wall of an SMT laser template. The method comprises the following steps that a nozzle arranged obliquely opposite to the pore wall of the SMT laser template sprays a liquid flow mixed with ground granules on the surface of the processed pore wall; and the nozzle moves at a certain speed to ensure that the liquid flow can be sprayed on the surface of the to-be-processed pore wall. Compared with the prior art, the method has the advantages that the method is more environment-friendly and processing efficiency is higher; and in the method, the pore wall of the SMT laser template is deburred and polished so as to facilitate subsequent processing such as solder paste printing and the like.
Description
Technical field
The present invention relates to a kind of method that the hole wall of SMT laser template is handled.
Background technology
Surface mounting technology (SMT) is the mainstream technology that present electronic product is made.All need to use printing stencil before electronic component mounts flow process, the preparation method of printing stencil has method for chemially etching and laser cutting method.The template of laser cutting is commonly called the SMT laser template, and it has characteristics such as positional precision height.But the hole wall after the cutting exists certain burr and roughness can influence the effect of print solder paste.Because the SMT laser template is generally thinner, and its hole is also less, and the area of hole wall is also less, and the method for removal burr commonly used and polishing is as mechanical grinding etc., all inapplicable.
Now common removal hole wall burr and the method for polishing generally adopt: by chemical immersion, electrochemistry or hyperacoustic mode.But chemistry or the not environmental protection of electrochemical mode, ultrasonic wave mode efficient is not high, and this has all seriously restricted the popularization of SMT laser template.
Summary of the invention
In view of this, technical problem to be solved by this invention provides a kind of relatively environmental protection, and the method with higher treatment effeciency is arranged, and the hole wall of SMT laser template is removed burr and polishing, so that carry out subsequent processes such as print solder paste.
The objective of the invention is to be achieved through the following technical solutions:
A kind of method that the hole wall of SMT laser template is handled comprises the steps:
The oblique nozzle that the hole wall of this SMT laser template is provided with is ejected into the wall of its handled hole wall with the liquid stream that is mixed with abrasive grains,
And described nozzle moves by certain speed, so that the liquid of its injection flows the wall of the pending hole wall of directive.
Wherein, abrasive grains is meant, the fine particle shape material of hard; Liquid can select to adopt water.
In general, the SMT laser template selects to adopt the metal or alloy material to make, especially stainless steel material.Adopt technique scheme, by nozzle institute atomizing of liquids stream will be preferably to the joint-cutting place of the hole wall of the SMT laser template after the laser cutting carrying out deburring and polishing.
Preferably, described abrasive grains is selected to adopt: size is 100 to 800 purpose silica sands, garnet, and diamond dust.
Contrast is found through test of many times, if abrasive grains, then causes the whole deformation of processed SMT laser template easily less than 100 orders; And if abrasive grains is greater than 800 orders, then polishing efficiency is low excessively.
Further, the thickness of described SMT laser template is 0.03 to 1 millimeter; Described abrasive grains is selected to adopt by 1: 2: 1 weight mixing match: size is that 300 purpose silica sands, size are that 400 purpose garnets and size are 600 purpose diamond dust.
Abovementioned technology is the embodiment that a kind of process test of many times contrasts resulting optimum, and three kinds of different abrasive grains mix according to the above ratio, can reach the effect that has complementary functions.Find through overtesting and analysis contrast: large diameter burr has good effect to a 300 purpose silica sands on the hole wall for removing; Two part of 400 purpose garnet has the best effect of improving for the stainless steel wall roughness; A 600 purpose diamond dust can guarantee that stainless steel wall light is clean.
Preferably, to press be 100 to 300Mpa to the liquid of described nozzle ejection liquid stream.
Find that through the overtesting contrast if liquid forces down in 100Mpa, then the ability of deburring is not enough, and treatment effeciency decline, do not reach the production demand; Be higher than 300Mpa if liquid is pressed, can make that then the SMT laser template causes tangible flexural deformation.
Further, the liquid of described nozzle ejection liquid stream is pressed and is 200Mpa.
Preferably, the diameter of described nozzle is 0.3 millimeter to 2 millimeters.
Find through the overtesting contrast, if the diameter of nozzle less than 0.3mm, can be easy to cause spray nozzle clogging; And if its diameter causes the skewness of the abrasive grains in the fluid jet that is sprayed easily greater than 2mm, make the quality of handling descend.
Further, the diameter of described nozzle is 1.3 millimeters.
Preferably, the angle between described nozzle and the described SMT laser template is 15 to 75 degree.
Find that through overtesting contrast when if the angle between described nozzle and the described SMT laser template is spent less than 15, the liquid that nozzle sprayed flows too small to stainless active force, deburring efficient is too low, has a large amount of injection streams not do work; And if this angle is when spending greater than 75, the smear metal power of the liquid stream that nozzle sprayed is excessive, will make the SMT laser template seem coarse rough.
Further, the angle between described nozzle and the described SMT laser template is 45 degree.
Preferably, along the axial direction of described nozzle ejection, the distance of described nozzle and described SMT laser template is 2 to 7 millimeters.
Find through the overtesting contrast, if axial direction along described nozzle ejection, the distance of described nozzle and described SMT laser template is less than 2 millimeters the time, the liquid stream that nozzle sprayed is handled in the initial segment of its jet, though can remove burr fast, but will cause darker vestige to the SMT laser template, not reach polishing action; If this distance is greater than 7 millimeters the time, the liquid stream that nozzle sprayed is handled in the dissipation section of its jet, be difficult to remove burr, so polishing effect is also bad.
Further, along the axial direction of described nozzle ejection, the distance of described nozzle and described SMT laser template is 5 millimeters.
Preferably, the translational speed of described nozzle is 3 to 10 mm/min.
Find through overtesting contrast, if the translational speed of described nozzle less than 3 mm/min, then the liquid of described nozzle ejection stream is to the wall action overlong time of its processing, polishing effect is relatively poor; And if the translational speed of described nozzle is then unclean to the removal of wall burr greater than 10 mm/min, polishing effect is not good yet.
Further, the translational speed of described nozzle is 7 mm/min.
Compared with prior art the invention has the advantages that, a kind of relatively environmental protection is provided, the method with higher treatment effeciency is arranged, the hole wall of SMT laser template is removed burr and polishing, so that it carries out subsequent processes such as print solder paste.
