The advantages and disadvantages of soft and hard board

1. The advantages of soft and hard board
There are many advantages of using Plaque flexible rigide, which are listed as follows:
1. The signal transmission distance is shortened and the speed is increased, which can effectively improve the reliability
The traditional signal transmission through the connector is [circuit board-connector-Soft plateConnecteur PCB], while the signal transmission of the soft and hard board is reduced to [circuit board-Soft plate- [carte de circuit], the signal transmission distance is shortened, Le problème de l'atténuation de la transmission du signal entre différents milieux est également réduit.. Generally, Les circuits sur les circuits imprimés sont en cuivre, Les bornes de contact du connecteur sont plaquées or, and the solder pins are It is fully tin plated and needs to be soldered on the circuit board with solder paste. Les transmissions de signaux entre différents médias s'atténuent inévitablement. If you switch to a flexible and hard board, Ces médias seront de moins en moins nombreux et la capacité de transmission du signal sera réduite.. Il peut être relativement amélioré, and the reliability of some products with higher signal accuracy requirements will help improve their reliability.
(2). It can effectively save the space on the circuit board and save the process of using connectors or HotBar
Because the rigid and flexible boards are already combined, Permet d'économiser de l'espace lors de l'utilisation initiale de connecteurs ou de bandes chaudes. For some flexible and rigid boards with high-density requirements, Nécessite moins d'un connecteur. Space is like picking up a treasure. Voilà., it also saves the cost of parts using the connector or the cost of the HotBar process. En outre, the space between the two rigid-flex board boards can be made tighter by eliminating the need for connectors.

3. Simplify product assembly and save assembly man-hours
The use of soft and hard board can reduce the man-hours of SMT parts, Parce que le nombre de connecteurs a diminué. It also reduces the man-hours for assembly of the whole machine, Parce qu'il élimine l'insertion Soft plate into the connector, Ou éliminer le processus de fabrication des barres chaudes. It also reduces the cost of parts management and inventory, Parce qu'il y a moins de Bom, so the management becomes less.
Deuxième, the shortcomings of the soft and hard board
After the introduction of the supplier, it is generally understood that if you simply compare the [soft and hard board] with [Soft plate+ circuit board + connector], the biggest disadvantage is [soft and hard] The price of the combined board is more expensive, and it may be more than the original price of the simple [Soft plate + hard board], but if you deduct the price of the connector or the cost of the HotBar, the price will be
It is possible that they will tend to be consistent, and the detailed costs may have to be actuarially calculated to have a clearer outline. Un autre inconvénient est que les pièces SMT et les fours peuvent avoir besoin de supports pour soutenir les pièces. Soft plate, Cela augmente en fait les coûts d'assemblage de SMT.
