Abstract
The invention is suitable for the machining field of printed circuit boards, provides a silk-screen printing method of overprinted characters, and aims to solve the problem how to overprint characters on a plugged circuit board after the phenomenon of printing leakage of the characters in traditional silk-screen printing. The silk-screen printing method of the overprinted characters comprises the steps of: providing the circuit board, wherein the circuit board comprises a device area plugged with electronic devices and a character overprinting area with local printing-leaked characters; providing character data to be overprinted on the character overprinting area; producing a film according to the character data; producing a corresponding screen according to the character overprinting area; fixedly mounting the screen on a silk-screen printer; performing the silk-screen printing for the characters in the character overprinting area; and baking and curing the characters. The silk-screen printing method produces the screen to conveniently overprint the characters on the circuit board plugged with the electronic devices. Like this, the whole waste of the circuit board due to local printing leakage of the characters can be effectively prevented, and the production cost is reduced.

For the circuit board of plug-in unit, owing to there is the stop of components and parts, half tone can not touch the plate face of circuit board, therefore, current screen printing technique is all carry out serigraphy character to the circuit board of non-plug-in unit, and idiographic flow comprises: design character data, to paint the film according to data light, make half tone, dress net, serigraphy character and rear roasting.But, carry out in the process of serigraphy character on a printed-wiring board, easily occur that batch is bitten the phenomenon of character.
Summary of the invention
The object of the present invention is to provide a kind of method for printing screen printing additional character, be intended to solve serigraphy character in prior art and occur that character is bitten after phenomenon on the circuit board of plug-in unit, how print additional the problem of character.
The embodiment of the present invention is achieved in that a kind of method for printing screen printing additional character, it is characterized in that, comprises the following steps:
There is provided circuit board, described circuit board comprises the components and parts region being inserted with electronic devices and components and the print character zone to be added locally biting character;
The character data printed additional to described print character zone to be added is provided;
According to the described character data make film;
Corresponding web plate is made according to described print character zone to be added;
Described web plate is fixedly installed on screen process press;
To character described in the serigraphy of described print character zone to be added; And
Bake and solidify described character afterwards.
Further, excise described web plate NULI character region, described NULI character region with described circuit board has the region of electronic devices and components or to have there is the region of intact character corresponding.
Further, the described web plate utilizing adhesive tape to be fixedly cut open.
Further, in described rear roasting step, comprise and baking sheet is provided and utilizes the step of character described in described baking sheet baking-curing.
Further, the temperature range of described baking sheet is 120-150 DEG C and baking time scope is 20-40 minute.
The method for printing screen printing additional character provided by the invention makes web plate according to the design feature of circuit board, the region making web plate be provided with character and described local character zone of biting is corresponding, namely the web plate corresponded is made, so that print additional character on the circuit board being inserted with electronic devices and components according to character zone that circuit board is locally bitten.Like this, effectively can avoiding because locally biting character, circuit board entirety being scrapped, reducing production cost.
Accompanying drawing explanation
