[Background technology] Printed wiring boards are made by layering multiple sheets of prepreg prepared by impregnating a base material such as paper with thermosetting resin such as phenolic resin and drying it, and then layering copper foil or other metal foil as necessary. This is done by heating and pressurizing it. The metal foil of the printed wiring board thus produced is then etched and punched to add to the printed wiring board.

After a printed wiring board is manufactured, it is stored or transported until it is processed into a printed wiring board and then stored, but in the past, it was necessary to prevent dust from adhering to the printed wiring board. It was simply something that was stored in a paper bag. For example, efforts are being made to lower the punching temperature in order to improve the dimensional accuracy of punching, but since the punching is simply stored in a paper bag, moisture can escape from the paper. It acts on the printed wiring board through the bag, and there is a risk that the printed wiring board may change its dimensions due to moisture absorption. If the accuracy is poor, the meaning will be lost.

Furthermore, when electronic components are mounted on a printed wiring board using an NC component mounting apparatus, there is a problem in that the pre-mounting position shifts as described above, causing trouble in the work performed by the NC component mounting apparatus.

Attempts have been made to prevent moisture absorption into the printed wiring boards by air-conditioning the room where the printed wiring boards are stored, but this requires a large amount of air conditioning equipment, and moreover, during transportation. Because air conditioning is difficult, fundamental solutions cannot be found.

[Objective of the Invention J The present invention has been made in view of the above points, and provides a printed wiring board that does not require air conditioning or the like and can prevent moisture absorption from occurring in printed wiring boards during storage and transportation. The purpose of this invention is to provide a method for preserving wiring boards.

[Disclosure of the Invention J However, the method for preserving a printed wiring board according to the present invention is as follows:
It is characterized by sealing the printed wiring board in a moisture-proof container, and by storing the printed wiring board in a state where it is isolated from moisture in the moisture-proof container, the printed wiring board has dimensions due to moisture absorption. The present invention will be described in detail below with reference to Examples.

Moisture-proof containers can be made by heat-sealing thermoplastic synthetic resin films such as polyethylene or polyvinylidene chloride.
Bags that can be opened, thermoplastic synthetic resin films that are laminated with an aluminum layer and sealed with heat seals, metal sealed containers whose openings are sealed with lids, and bags whose openings are sealed with lids. A sealed container made of synthetic resin or the like can be used. In short, anything can be used as long as it can block the passage of moisture and seal the opening. As the aluminum-laminated synthetic resin bag, Aluminum Saranefukus manufactured by Asahi Dow Co., Ltd., which is made of laminated layers of nylon, aluminum, polyethylene, and polyvinylidene chloride, can be used as a commercially available product.
As the polyvinylidene chloride bag, a commercially available product such as Lanex manufactured by Asahi Dow Co., Ltd. can be used. The printed wiring board is then placed in this container and sealed to preserve it during storage and transportation.The printed wiring board is made of paper and is impregnated with 7 ml of sugar bean. It is particularly effective to use the cured WK7 x Nord laminate because it easily absorbs moisture and is greatly affected by moisture absorption.

Here, the results of an experiment conducted to confirm the effect of sealed storage are shown below. This was heated at 20℃, 80%R
In a room at 30°C and 88% RH, we stored unsealed bags, heat-sealed bags in 60μ thick polyethylene bags, and 150μ thick aluminum laminate bags (
Each printed wiring board was heat-sealed and stored in aluminum Saranex, and the dimensional changes and weight changes of each printed wiring board were measured. The results are shown in the graph in the attached figure.The results of the graph show that the unsealed product (comparative example) had larger dimensional and weight changes (while the product sealed in a polyethylene bag (Example 1) and the aluminum laminate It can be sealed in a bag, and especially when sealed in an aluminum laminate bag, moisture is almost completely blocked and there is almost no dimensional or weight change, and it is confirmed that it is highly effective.

[Advantageous Effects of the Invention 1] As described above, in the present invention, the printed wiring board is sealed and stored in a moisture-proof container, so the printed wiring board is protected from moisture in the air. This prevents the printed wiring board from absorbing moisture or dehumidifying it without the need for air conditioning, thereby reducing dimensional changes in the printed wiring board. .
