技术领域
本发明涉及摇杆电位器技术领域,具体涉及一种电位器用树脂板电阻片的改良型印刷工艺。
背景技术
随着科学技术的日新月异,不断发展,电极片常用于电器、仪表趋向多功能化及微型化方面,在多个领域都有应用,如摇杆电位器、工具机、汽车控制元件、家电产品、电子玩具等,一般在电子产品中的电阻片表面需要印刷电阻抗值为1kΩ-500kΩ的碳膜,用以控制输出阻抗。常规的电阻片印刷工艺,一般是先在基板上印刷导电线路,然后在导电线路上选择性覆盖碳膜,得到的电阻片厚度大,影响电位器的尺寸。
发明内容
针对以上问题,本发明提供一种电位器用树脂板电阻片的改良型印刷工艺,工艺简单,所制作得到的电阻片厚度小。
为实现上述目的,本发明通过以下技术方案来解决:
一种电位器用树脂板电阻片的改良型印刷工艺,包括以下步骤:
a、设计丝网图案,并制作丝网,设置丝网的厚度为8~13μm;
b、使用塑胶本体或电木板作为基板,对基板的印刷区域进行挖沟槽,所形成的沟槽深度为8μ~20μ;
c、将丝网铺设于基板板面上,用刮胶将导电金属浆通过丝网印刷在基板板面上,干燥后印刷区域形成导电金属线路;
d、将丝网铺设于导电金属线路上,用刮胶将导电碳浆通过丝网印刷在基板板面上,干燥后沟槽位置形成电阻碳膜,电阻碳膜在基板上的厚度为3~5μm;
e、将印刷后的基板放置于热压治具内热压,热压过程中温度为180~270℃、压力为2KG~8KG,热压后电阻碳膜在基板上的厚度为1~3μm。
具体的,所述步骤c中,导电金属浆为金属银浆。
具体的,所述步骤c中,干燥的温度为145~155℃。
具体的,所述步骤d中,导电碳浆需印刷在基板沟槽上。
具体的,所述步骤d中,干燥的温度为165~175℃。
具体的,所述步骤e中,热压治具的温度为180~230℃,下压压力为2~5KG,热压时间为2~6min。
具体的,所述步骤e中,热压治具内具有离型性不锈钢片,使用离型性不锈钢片对电阻碳膜膜面进行热压。
本发明的有益效果是:
本发明的一种电位器用树脂板电阻片的改良型印刷工艺,先对印刷位置进行挖沟槽,然后再印刷制作导电金属线路、电阻碳膜,使电阻碳膜成型于沟槽内,然后对电阻碳膜热压,使最终成型的电阻碳膜被压缩,从而减少了电阻片的厚度,工艺简单,所制作得到的电阻片厚度小。
具体实施方式
为了能进一步了解本发明的特征、技术手段以及所达到的具体目的、功能,下面结合具体实施方式对本发明作进一步的详细描述。
实施例1
一种电位器用树脂板电阻片的改良型印刷工艺,包括以下步骤:
a、设计丝网图案,并制作丝网,设置丝网的厚度为8~13μm;
b、使用塑胶本体或电木板作为基板,对基板的印刷区域进行挖沟槽,所形成的沟槽深度为8μ~20μ;
c、将丝网铺设于基板板面上,用刮胶将金属银浆通过丝网印刷在基板板面上,干燥的温度为145~155℃,干燥后印刷区域形成导电金属线路;
d、将丝网铺设于导电金属线路上,用刮胶将导电碳浆通过丝网印刷在基板板面上,导电碳浆需印刷在基板沟槽上,干燥的温度为165~175℃,干燥后沟槽位置形成电阻碳膜,电阻碳膜在基板上的厚度为3~5μm;
e、将印刷后的基板放置于热压治具内热压,为了避免电阻碳膜热压后黏在热压模具上,造成电阻碳膜脱离基板,热压治具内具有离型性不锈钢片,使用离型性不锈钢片对电阻碳膜膜面进行热压,热压过程中温度为180~230℃、压力为2KG~5KG,热压时间为2~6min,热压后电阻碳膜在基板上的厚度为1~3μm,热压后电阻碳膜被压缩,从而减少了电阻片的厚度。
以上所述实施例仅表达了本发明的1种实施方式,其描述较为具体和详细,但并不能因此而理解为对本发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
