Resin plugging process
1. Definition
Resin plugging process refers to the use of resin to plug the buried holes in the inner layer, and then press, which is widely used in high-frequency board and HDI board; it is divided into traditional screen printing Resin Plugging and vacuum resin plugging. Generally, the production process of the product is traditional screen printing resin plug hole, which is also the most common process in the industry.
2. Process
Pre process — drilling resin hole — electroplating — resin plug hole — ceramic grinding plate — drilling through hole — electroplating — post process
3. Electroplating requirements
According to the copper thickness requirements, electroplating. After electroplating, the resin plug hole was sliced to confirm the concavity.
Vacuum resin plugging process
1. Definition
Vacuum screen printing plug hole machine is a special equipment for PCB industry, which is suitable for PCB blind hole resin plug hole, small hole resin plug hole, and small hole thick plate resin plug hole. In order to ensure that there is no bubble in resin plug hole printing, the equipment is designed and manufactured with high vacuum, and the absolute vacuum value of vacuum is below 50pA. At the same time, the vacuum system and screen printing machine are designed with anti vibration and high strength in structure, so that the equipment can operate more stably.
2. Difference
The process flow of vacuum plug hole is close to that of traditional screen printing. The difference is that the product is in a vacuum state in the plug hole production process, which can effectively reduce the bad effects such as bubbles.
