How to make flexible and hard board production

The birth and development of FPC and PCB gave birth to a new product of Plaques souples et rigides. Therefore, Les panneaux flexibles rigides sont des panneaux flexibles et rigides, which are combined according to the relevant process requirements after pressing and other processes to form a circuit board with FPC characteristics and PCB characteristics.
After the FPC Production de carton souple, it must go through those processes to complete the production of the soft-hard board.
(1). Punching
Drill holes on the FR4 circuit board and Film de polypropylène, La conception du trou de positionnement est différente de celle du trou général. After the punching is completed, Browning est nécessaire.
(2). Riveting
Laminate the Plaqué de cuivre, Adhésif polypropylène, and FPC Carte de circuit et bien positionnée. The original old process is to laminate and produce the laminate step by step, Mais c'est une perte de temps.. After many attempts, Il s'avère que le processus d'empilage peut être terminé en même temps.
3.. Laminate
This is a relatively complete step in the production of rigid-flex board. La plupart des matériaux sont intégrés pour la première fois. Forster., the bottom layer of copper clad laminate and PP film, Ce qui précède FPC Soft plate produced in the previous process, Et dans FPC soft board. PP film, then place the last layer of copper clad laminate. Tous les matériaux à stratifier sont placés et pressés ensemble dans l'ordre.
Shenzhen Zhongke Circuit Technology Co., Ltd.., Ltd. is a high-precision PCB multi-layer circuit board manufacturer, focusing on PCB circuit boards, Carte de circuit HDI, Plaques souples et rigidess, Carte de circuit haute fréquence/high-frequency circuits PCB, PCB Blind Buried through hole, long strip, Carte de circuit extra longue, Longue carte de circuit, double-sided extra long board, Carte de circuit extra longue, special circuit board, Attendez..


Comment produire du carton flexible

4. Gong Banbian (also known as trimming)
That is to remove the part of the PCB circuit board where there is no circuit at the edge of the circuit board and the part that is not going to be made in the future. Après, Il est nécessaire de mesurer l'expansion et la contraction excessives du matériau.. Because the PI used in the production of flexible boards in time is also expansion and contraction, Cela a une grande influence sur la production de circuits imprimés.
5. Drilling
This step is the first step of one step of conducting the entire PCB circuit board, Les paramètres de production doivent être produits conformément aux paramètres de conception..
6. Épluchage, plasma treatment
First, Enlèvement des scories provenant du forage des PCB, and then use plasma cleaning to clean the through holes and the board surface.
7. Immersion copper
This step is the process of electroplating through holes, Aussi connu sous le nom de métallisation des trous. Realize through-hole power conduction.
8. PCB circuit board surface plating
Partially electroplating copper on the upper surface of the electroplating hole makes the copper thickness above the through hole exceed a certain height of the copper clad board surface.
9. Outer dry film positive film production
The same as the process of making anti-corrosion dry film of FPC soft board, make the circuit to be Attendez.hed on the copper clad board. Une fois le développement terminé, check the circuit.
10. Graphic plating
After the initial copper sinking, Effectuer un placage graphique, and the current time and copper plating wire are used according to the design requirements to reach a certain electroplating area.
11. Alkaline Attendez.hing
12. Print solder mask
This step has the same effect as that of the soft board protective film. Nous voyons que les cartes PCB sont généralement vertes. This step is generally called green oil printing. Une fois l'impression terminée, the inspection is carried out. Les clients ont également besoin d'autres encres de soudage, such as butter, Huile bleue, red oil, Huile blanche, black oil, etc., with photosensitive and matte.
- 13.. Open the lid with the gong
The gong opening cover is also called the cover opening, Dans quelle zone se trouve le softboard, but the area not needed by the hard board is laser cut to expose the soft board.
- 14.. Curing is also a baking process
15. Traitement de surface: trempage de l'or, spray tin, OSP, Immersion silver, Trempage de l'étain, gold plating, etc.
En gros, En ce moment, a rigid-flex board (FPCB) has been manufactured, and only the metallization treatment is required on the surface of the circuit board, Peut empêcher l'usure et l'oxydation. Generally, this process is to soak the circuit board in a chemical solution, Les éléments métalliques de la solution sont densément répartis sur la carte de circuit.
16. Police imprimée/printed text
The positions of the parts to be assembled and some basic product information are printed on the rigid-flex board in the form of characters.
17. Flying probe test/test fixture test
This is an inspection process for whether the PCB circuit board is qualified. The test items are tested for electrical properties according to customer requirements. Les essais comprennent généralement des essais d'impédance, open and short circuit test and so on.
18.FRQ final inspection
19. Packaging and shipping
There are many methods for circuit board packaging. Generally, La plupart des fabricants utilisent des sacs pour les séparer, and then use a vacuum packaging machine to vacuum-pack the flexible and rigid boards.
