壓力塞孔機與真空塞孔機：PCB 塞孔設備的對比與選擇指南

在 PCB 生產中，塞孔環節至關重要，壓力塞孔機和真空塞孔機作為專用設備，因工作原理、適用場景等差異，為不同生產需求提供了多樣選擇。

一、工作原理差異

• 壓力塞孔機：依靠增壓系統產生壓力，將樹脂等塞孔材料壓入 PCB 孔內，以此達成塞孔目的。這種直接加壓的方式，簡單直接地實現材料填充。

• 真空塞孔機：運用真空技術，通過抽真空營造無氣環境，利用吸附作用使工件表面小孔和凹槽被塞住，同時讓工件與背板緊密貼合，保障塞孔的高精度與高質量。

二、適用材料與范圍

• 壓力塞孔機：對各種材料和板厚的電子線路板都有良好適應性，尤其在樹脂塞孔方面表現出色，能提供足夠壓力保證孔的飽滿度，應用場景較為廣泛。

• 真空塞孔機：主要以樹脂材料進行塞孔，在 HDI 高密度互連板等高端 PCB 板領域優勢明顯。真空環境有效解決了藏氣問題，極大提升了塞孔質量，滿足高端產品對品質的嚴苛要求。設備的優勢：1. 設備的安全性：有三道安全防護保護裝置，確實生產人員的絕對安全。2.長時間運行穩定性：可持續生產一個星期。3.自帶參數設定記憶功能及在線遠程支持。4.對批量板的生產效率提高百分之二十至百分之四十。5.適用于塞通孔、盲孔、背鉆孔、銅漿塞孔等。

三、成本與維護考量

• 壓力塞孔機：成本相對較低，但為實現良好塞孔效果，需要較高壓力，這對設備性能提出了較高要求，在設備選型和維護時需重點關注壓力相關部件。

• 真空塞孔機：由于要維持真空工況，設備成本較高。不過，其整體生產效率更高，運行穩定，長期來看，在提升生產效益方面具有一定優勢。

四、應用領域側重

• 壓力塞孔機：在電子線路板生產、包裝、印刷等多個行業都有應用，特別是在解決“黃金孔”問題上表現突出，為相關行業提供了有效的解決方案。

• 真空塞孔機：適用于 PCB 通孔、直孔、盲孔、鉆孔等多種孔型的塞孔處理，尤其在高精度、高品質要求的高端 PCB 板塞孔中占據重要地位。

五、上海歐贊自動化科技設備有限公司的優質方案

1. 壓力塞孔機：面對“黃金孔”難題，上海歐贊的高精度壓力塞孔機表現出色。通過將油墨濃度調整至 300 - 500 的黏度，確保塞孔飽滿，有效減少烘烤時孔口的收縮力，避免孔口油墨變薄現象，徹底解決“黃金孔”問題，為客戶消除后顧之憂。

2. 真空塞孔機：性能**，塞孔方式靈活，既可選擇選擇性塞孔，也可進行整板塞孔。兼容樹脂、油墨、銀膏、銅槳等多種材料，滿足不同生產需求。自研超高真空系統抽真空速度快，真空度高達 50pa，有效解決絲印時氣泡產生的質量問題。產能突破 3 片每分鐘，1 刀完成塞孔且無需返工，實現高效率與高品質的完美結合，受到眾多 PCB 行業百強企業的關注。

   

六、選擇建議

如果對生產效率和產品質量有較高追求，真空塞孔機憑借其高效穩定、高品質的特點，可能是更優選擇；而對于一些有特定塞孔需求，如對壓力控制精度要求高、需要針對特定材料或孔型進行精確塞孔的情況，壓力塞孔機或許能提供更精準的控制和更高的穩定性。在實際選擇時，需綜合考量材料類型、材料厚度、加工要求、預算和生產量等因素，同時選擇優秀廠家，確保產品質量和售后服務。上海歐贊自動化科技設備有限公司憑借成熟的生產體系和非標定制服務，為不同客戶提供多樣化、個性化的解決方案，值得關注與選擇。

Pressure plug hole machine and vacuum plug hole machine: comparison and selection guide for PCB plug hole equipment

In PCB production, the plug hole process is crucial. Pressure plug hole machines and vacuum plug hole machines, as specialized equipment, provide diverse choices for different production needs due to differences in working principles and applicable scenarios.
