Description
Technical field
It is good to the present invention relates to thickness homogeneous and surface smoothing property, for example is suitable for burning till film and burning film forming method of manufacture of conductive film, insulating film, adhesive film etc.
The present invention relates to be used to carry the delivery vehicles of substrates such as flexible print circuit board and the method for manufacture of delivery vehicles.
Background technology
Burn film forming coating fluids (printing ink) as being used to make conductive film, insulating film, adhesive film etc., for example, prepare through inorganic particulate is dispersed in the vehicle that dissolving resin obtains in solvent.And, through silk screen printing or dip coated method etc. behind the coating fluid of coating preparation on the substrate, through dry, burn till, make and burn till film.
Recently, follow miniaturized, the high performance of electronic component, the level that requires of the film forming physicals of burning that forms through silk screen printing, dip coated method is uprised.
For example, in the delivery vehicles of flexible print circuit board substrates such as (FPC), in order to ensure in the space of production scene, preferably vertical placement substrate is managed when FPC is installed, and requires the demand in the production scene of higher binding property and so on to increase.
In the method for manufacture of the delivery vehicles of existing substrate, have following problem: in order to expose four jiaos of aluminium base, with masking tape aluminium coating substrate four jiaos carry out the scraper plate coating through one piece of one piece of handwork, and spended time is produced rate variance.
In addition, the coating fluid that contains the vehicle that ethyl cellulose dissolved obtains in solvent is easy to generate following problem: contain the solvent after the coating state film be called as and ooze out or the increase (increase of surface covered) of the sagging mobile size that causes or dry and result from the softening of resin and filming of producing sagging etc. when burning till.
In addition, there is following problem in the coating fluid that contains the vehicle that dissolving vinyl resin and polyvinyl butyral resin obtain in solvent: because leveling characteristics is poor, binding property is strong excessively, and therefore, the coating fluid wire drawing is also extended, and therefore, operation property is poor.
In addition, motion have a kind of coating fluid that contains the dimethyl silicone polymer composition containing that comprises YSR 3286 at least (for example, with reference to TOHKEMY 2009-292970 communique, TOHKEMY 2009-147353 communique, and No. 4438896 communique of patent).But there is following problem in this coating fluid that comprises dimethyl silicone polymer composition containing: stringiness is strong, and when silk screen printing, with respect to moving of squeegee, the version that leaves of silk screen postpones film coated surface roughen thus.
Therefore; Present situation is that following burning till film and burn film forming method of manufacture preferably is provided rapidly; Leveling characteristics after the film forming coating of said burning is excellent and be difficult for producing oozing out of filming or sagging and sagging etc. dry and filming when burning till, and thickness homogeneous and dimensional precision are high.
The flexible print circuit board that electronic component is installed (FPC) of semi-conductor etc. is the substrate of film like, therefore, as far as monomer, is easy to generate distortion or warpage etc.Therefore; Under the situation of the installation of carrying out electronic component on the FPC, medicine cleaning, plasma treatment; Generally speaking; Use has bonding coat on substrate the anchor clamps that are called delivery vehicles carry out (for example, with reference to japanese kokai publication hei 7-22795 communique, TOHKEMY 2004-71863 communique and TOHKEMY 2004-158477 communique).
When on such delivery vehicles, FPC being set, having on the FPC under the situation of electronic components such as mounted semi-conductor, its part becomes protuberance and hinders FPC is set on delivery vehicles.Therefore, need on delivery vehicles, form hole portion in advance and miss protuberance.But delivery vehicles becomes the stepped construction of the different differing materials of material and the hardness of substrate and bonding coat, therefore, exists in when forming hole portion, cracks on any in substrate and bonding coat and problem such as fold.For example, at the substrate that uses metal such as aluminium as delivery vehicles, use under the situation of softish organic materials as the bonding coat of delivery vehicles such as silicone resin, both physical property difference is big, therefore is difficult to form hole portion.And then, there is following problem: on the bonding coat of delivery vehicles,, therefore, make the yield rate variation of delivery vehicles in case the rubbish or the grinding medicament (oil) that adhere to when forming hole portion just are difficult for taking off.
Summary of the invention
The object of the present invention is to provide leveling characteristics after coating excellent and be difficult for producing oozing out of filming or sagging, and dry and filming when burning till is sagging etc., what thickness homogeneous and dimensional precision were high burns till film and burns film forming method of manufacture.
The method of manufacture that the object of the present invention is to provide high-quality delivery vehicles and can make the delivery vehicles of this delivery vehicles efficiently; Said delivery vehicles not on substrate the rubbish when residual formation hole portion or recess, grind medicament (oil), or coating fluid non-cohesive in the hole inside of portion or recess.
