Realize the function of application.
The technical process of flexible circuit board provided in the present embodiment is introduced in detail below：
Firstly, it is necessary to carry out the sawing sheet of flexible circuit board.In addition to some materials, material used in flexible circuit board is basic
It is all web-like.Since not all process all has to be processed with winding technique, some processes must be cut into piece
Shape is just capable of processing, and such as the drilling of the plated through-hole of double-faced flexible printed board, can only be drilled at present with sheet form, so double
Flexible circuit board the first procedure in face is exactly sawing sheet.
The ability to bear of the external power of flexible copper-clad foil laminate is very poor, it is easy to injured.If be damaged in sawing sheet
The generation of the qualification rate of later each process will be seriously affected.Therefore, even if appearing to be foolproof sawing sheet, in order to guarantee material
The quality of material, it is also necessary to attach great importance to.If amount is fewer, craft cutter or hobboing cutter cutter can be used, in high volume,
Automatic shearing machine can be used.
Then, it is also necessary to drilling conducting be carried out to flexible circuit board, the through-hole of flexible circuit board is as rigid printed board
Digital control hole drilling can also be used, but is not suitable for the hole machined of winding two-sided metallization hole circuit.With the high density of circuitous pattern
Change the small-bore with plated through-hole, in addition there is certain limit in the aperture of digital control hole drilling, present many new drilling techniques are paid
Practical application.These new drilling techniques include plasma borrosion hole, laser drill, the punching of micro-aperture, chemical borrosion hole etc.,
The pore-forming requirement of winding technique is more easily satisfied than digital control hole drilling for these drilling techniques.
Then also device to hole is needed to metallize, the hole metallization of flexible circuit board and the mesoporous metal technique of rigid printed board
It is essentially identical.Occurs substituted chemistry plating in recent years, using the directly electroplating technology for forming carbonaceous conductive layer technology.Flexible printed circuit
Hole metallization this technology has also been introduced.Flexible circuit board needs special stationary fixture, fixture is not only due to its softness
Flexible printed circuit can be fixed, and must also stablized in the plating solution, otherwise copper facing is in uneven thickness, this is also in etching work procedure
In cause break and bridge major reason.To obtain uniform copper plate, it is necessary to tighten flexible printed circuit in fixture,
But also it to work hard in the location and shape of electrode.Hole metallization outsourcing processing will avoid being contracted out to no flexibility as far as possible
The factory of printed board hole experience, if without the dedicated plating line of flexible printed circuit, hole quality not can guarantee.
Then also need to clean copper foil surface, in order to improve the adhesive force of exposure mask against corrosion, be coated with exposure mask against corrosion it
Before copper foil surface is cleaned, even if such simple procedures are also required to pay special attention to for flexible printed circuit.
General cleaning has chemical cleaning technology and mechanical milling tech, and when for manufacture precision graphic, most of occasions are
Two kinds of clear stream techniques are combined and are surface-treated.Mechanical lapping using throw brush method, throw brush material is really up to the mark can be to copper
Foil causes to damage, too soft and can grind insufficient.Usually use nylon bruss, it is necessary to carefully be ground to the length and hardness of throwing brush
Study carefully.Using two throwing brush rolls, the upper surface of conveyer belt, direction of rotation and belt direction of transfer are placed on the contrary, but brushing at this time if thrown
Roller pressure is excessive, and substrate will be elongated by very big tension, this is the one of the major reasons for causing change in size.
If copper foil surface processing is not clean, the adhesive force with exposure mask against corrosion can thus reduce etching work with regard to poor
The qualification rate of sequence.Recently due to also can be omitted surface cleaning process in the case of the raising single sided circuits of copper foil plate quality.
Finally, it is also necessary to carry out the coating of resist, the coating method of present resist is according to the precision of circuitous pattern
It is divided into following three kinds of methods with yield：Silk screen method, dry film photoresist process, liquid resist photoresist process.
On the basis of embodiment shown in Fig. 1, the utility model is according to a kind of flexibility again and shown in exemplary embodiment
Circuit board, including：
Flexible circuit board ontology 1, interconnecting piece and extension, wherein interconnecting piece includes at least first connecting portion 3 and second
Interconnecting piece 4, extension include the first extension 31 and the second extension 41, first connecting portion 3 by the first extension 31 with it is soft
Property circuit board main body 1 connect, second connecting portion 4 is connect by the second extension 41 with flexible circuit board main body 1；Wherein, first
Interconnecting piece 31 with the first connector on input equipment for connecting, and second connecting portion with second on output equipment for connecting
Device connection, and fluting portion 32, institute are provided at least one extension in the first extension 31 and the second extension 41
It states and offers at least one through-hole 321 in fluting portion.
Wherein, the opening shape of the first through hole opened up in the fluting portion 32 of the first extension 31 is the first rectangular shape,
The opening shape of the second through-hole opened up in the fluting portion 32 of second extension is the second rectangular shape, also, first through hole
Center is respectively positioned in first straight line, and the center of the second through-hole is respectively positioned in second straight line.
May be used also to further improve stress distribution of the flexible circuit board in bending so that stress distribution is more uniform
It is parallel to set first straight line to the end face of one end with first connecting portion 3 far from the first extension 31；Second straight line and the
The end face of the one end of two interconnecting pieces 4 far from the second extension 41 is parallel.
Further, it is also possible to set first through hole to along the equidistant array arrangement in first straight line direction, the second through-hole is set as
Along the equidistant array arrangement in second straight line direction.
