Description
Technical field
The present invention relates to wiring board manufacturing technology, the wiring board manufacturing technology that especially a kind of cost is low, efficiency is high.
Background technology
In order to adapt to the needs of the aspect such as environment for use, installation, the size of wiring board must meet corresponding designing requirement.Therefore, in manufacturing process, wiring board must be processed to the size meeting dimensional requirement.In prior art, the wiring board dimensioned method usually adopted is stamping or CNC (ComputerizedNumericalControl computer numerical control (CNC) machining center) processing method.Adopt plunger approach, edges of boards are crude, and edge may occur that layering causes scraps; Adopt CNC processing method, the process time is long, and milling cutter consumption greatly, costly.
Summary of the invention
Technical problem to be solved by this invention is to provide the wiring board manufacturing technology that a kind of cost is low, efficiency is high.
For solving the problems of the technologies described above, the invention provides a kind of Wiring board processing method, comprising the following steps:
A. first preprocessing is carried out to wiring board; Compared with dimensional requirement, the limit of the wiring board working position after preprocessing
Edge remains with allowance;
B. carry out fine finishining to the wiring board after step a preprocessing according to dimensional requirement, the allowance retained in step a is all or part of elimination in finishing passes.
In the inventive method, the allowance that in step a, the edge of wiring board working position retains will all be eliminated in the finishing passes of step b, or part eliminates (consideration tolerance), therefore preprocessing process dimension precision requirement is low, can complete preprocessing process with speed faster, low required precision is simultaneously also for selecting low cost cutter to create condition; After preprocessing, make wiring board meet size and required precision by fine finishining again.
On this basis, further:
Preprocessing process in step a is stamping process, or the process for adopting waste and old milling cutter to drag for limit in advance.Preprocessing adopts stamping processing, can make preprocessing process rapidly and efficiently; The issuable crude and lamination of edges of boards also can be eliminated in the finishing passes of step b.Preprocessing adopts waste and old milling cutter to drag for limit in advance, also can enter with fast speed
OK, saved the cost of charp tool simultaneously.
Finishing passes in step b is the process adopting CNC (ComputerizedNumericalControl computer numerical control (CNC) machining center) deburring.In finishing passes, wiring board is machined to the size range of requirement.
The allowance that the edge of the wiring board working position in step a after preprocessing retains can be 0.05mm-0.3mm.The control of allowance can process complexity, processing dimension, process equipment, processing speed according to wiring board
The actual conditions such as degree are determined.
The invention has the beneficial effects as follows: process is simple, it is convenient to implement, and can take into account working (machining) efficiency and processing cost simultaneously, can improve productive rate, cuts down finished cost under the prerequisite keeping machining accuracy.
[detailed description of the invention]
Embodiment one
A kind of detailed process of employing the inventive method processing line plate is:
A. first stamping processing method is adopted to carry out preprocessing to wiring board; Compared with dimensional requirement, the wiring board after preprocessing has the allowance of 0.05mm-0.3mm;
B. according to dimensional requirement, CNC fine finishining is carried out to the wiring board after step a preprocessing, allowance all or part of elimination in finishing passes of the wiring board edges of boards 0.05mm-0.3mm after step a preprocessing, the size conforms dimensional requirement of fine finishining rear board.
Embodiment two
A kind of detailed process of employing the inventive method processing line plate is:
A. first preprocessing is carried out to wiring board: adopt waste and old milling cutter to carry out CNC to wiring board and drag for limit in advance; Compared with dimensional requirement, the wiring board after preprocessing has the allowance of 0.05mm-0.3mm; B. according to dimensional requirement, CNC fine finishining is carried out to the wiring board after step a preprocessing, pre-through step a
Allowance all or part of elimination in finishing passes of the wiring board edges of boards 0.05mm-0.3mm after processing, the size conforms dimensional requirement of fine finishining rear board.
In step a, lower to dimension precision requirement owing to dragging for limit in advance, so speed can double than normally dragging for limit; Wiring board in step a through dragging for limit in advance, CNC fine finishining processing capacity in step b is very little, CNC fine finishining speed in such step b also can be accelerated, and decreases the consumption of cutter in CNC finishing passes simultaneously, substantially increases cutter life.
During concrete enforcement, can comprehensively wiring board processing capacity, stamping mould therefor expense, process time etc. because of usually consider add
Work efficiency rate and cost, to select suitable pre-process method.If because of processing capacity is little or stamping so the too high unit cost of preprocessing that causes of die cost is higher, then preprocessing process can adopt waste and old milling cutter to drag for the method on limit in advance to wiring board.Allowance change as the case may be can choose different margin range, determine allowance need consider factor comprise but
Be not limited to: wiring board processing complexity, processing dimension, process equipment, process velocity etc.
Above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all be considered as belonging to protection scope of the present invention.
