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 meet the size of dimensional requirement. In prior art, the wiring board dimensioned method conventionally adopting is stamping or CNC (ComputerizedNumericalControl computer numerical control (CNC) machining center) processing method. Adopt stamping method, edges of boards are crude, and edge may occur that layering causes and scraps; Adopt CNC processing method, the process time is long, and milling cutter consumption is large, expense is high.
[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, comprise the following steps:
A. first wiring board is carried out to preprocessing; Compared with dimensional requirement, the limit of the wiring board working position after preprocessing
Edge remains with allowance;
B. the wiring board after step a preprocessing is carried out to fine finishining according to dimensional requirement, the allowance retaining in step a is all or part of elimination in fine finishining process.
In the inventive method, in step a, the allowance of the Edge preserving of wiring board working position will all be eliminated in the fine finishining process of step b, or part is eliminated (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 for adopting waste and old milling cutter to drag in advance the process on limit. 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 fine finishining process of step b. Preprocessing adopts waste and old milling cutter to drag in advance limit, also can enter with fast speed
OK, saved the cost of charp tool simultaneously.
Fine finishining process in step b is for adopting the process of CNC (ComputerizedNumericalControl computer numerical control (CNC) machining center) deburring. In fine finishining process, wiring board is machined to the size range of requirement.
The allowance of the Edge preserving of the wiring board working position in step a after preprocessing can be 0.05mm-0.3mm. The control of allowance can be processed 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 under the prerequisite that keeps machining accuracy, improve productive rate, cut down finished cost.
[detailed description of the invention]
Embodiment mono-
[0014] adopt a kind of detailed process of the inventive method processing wiring board to be:
A. first adopt stamping processing method 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. the wiring board after step a preprocessing is carried out to CNC fine finishining according to dimensional requirement, the allowance all or part of elimination in fine finishining process of wiring board edges of boards 0.05mm-0.3mm after step a preprocessing, the size conforms dimensional requirement of fine finishining rear board.
Embodiment bis-
Adopt a kind of detailed process of the inventive method processing wiring board to be:
A. first wiring board is carried out to preprocessing: adopt waste and old milling cutter to carry out CNC to wiring board and drag in advance limit; Compared with dimensional requirement, the wiring board after preprocessing has the allowance of 0.05mm-0.3mm; B. the wiring board after step a preprocessing is carried out to CNC fine finishining according to dimensional requirement, pre-through step a
The allowance all or part of elimination in fine finishining process of wiring board edges of boards 0.05mm-0.3mm after processing, the size conforms dimensional requirement of fine finishining rear board.
In step a, owing to dragging in advance, limit is lower to dimension precision requirement, so speed can double than normally dragging for limit; Wiring board in step a through dragging in advance limit, CNC fine finishining processing capacity in step b is very little, CNC fine finishining speed in step b also can be accelerated like this, has reduced the consumption of cutter in CNC fine finishining process simultaneously, has greatly improved cutter life.
When concrete enforcement, comprehensively add because of usually consideration wiring board processing capacity, stamping mould therefor expense, process time etc.
Work efficiency rate and cost, to select suitable pre-process method. So if because processing capacity is little or the too high unit cost of preprocessing that causes of stamping die cost is higher, preprocessing process can adopt waste and old milling cutter wiring board to be dragged in advance to the method on limit. Allowance can variation as the case may be chosen different margin range, determine that factor that allowance need to be considered comprises 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, can also make some simple deduction or replace, all should be considered as belonging to of the present invention
Protection domain.
