\u306b\u3064\u3044\u3066 batch coating process<\/strong> \u3067 \u30b3\u30f3\u30d5\u30a9\u30fc\u30de\u30eb\u30fb\u30b3\u30fc\u30c6\u30a3\u30f3\u30b0<\/strong><\/a> refers to applying coating to multiple PCBs at the same time in grouped cycles rather than continuously. This method is widely used in PCB\u30a2\u30bb\u30f3\u30d6\u30ea<\/strong>, \u30d7\u30ed\u30c8\u30bf\u30a4\u30d7PCB\u30a2\u30bb\u30f3\u30d6\u30ea<\/strong>, and small-to-medium scale SMT\u30a2\u30bb\u30f3\u30d6\u30ea<\/strong>, where flexibility and cost control are important.<\/p>\n

\"What
What is batch coating process<\/figcaption><\/figure>\n

How batch coating works<\/strong>
In a batch process, a group of assembled PCBs is prepared, masked, and coated together using methods such as dipping, spraying, or brushing. After coating, all boards in the batch go through a shared drying or curing cycle. Once completed, the next batch is processed.<\/p>\n

Common batch coating methods<\/strong><\/p>\n

\u30c7\u30a3\u30c3\u30d7\u30b3\u30fc\u30c6\u30a3\u30f3\u30b0<\/strong>
PCBs are submerged into a tank of \u30b3\u30f3\u30d5\u30a9\u30fc\u30de\u30eb\u30fb\u30b3\u30fc\u30c6\u30a3\u30f3\u30b0<\/strong> material and then withdrawn at a controlled speed. This ensures full coverage but requires proper masking in PCB\u30a2\u30bb\u30f3\u30d6\u30ea<\/strong>.<\/p>\n

Manual or spray coating<\/strong>
Operators or semi-automatic spray systems apply coating to multiple boards placed in racks or fixtures. This is common in \u30d7\u30ed\u30c8\u30bf\u30a4\u30d7PCB\u30a2\u30bb\u30f3\u30d6\u30ea<\/strong><\/a> due to its flexibility.<\/p>\n

\u30d6\u30e9\u30b7\u30b3\u30fc\u30c6\u30a3\u30f3\u30b0<\/strong>
Used mainly for rework or small batches, where precision is needed but production volume is low.<\/p>\n

Key features of batch coating<\/strong><\/p>\n

Grouped processing<\/strong>
Multiple boards are coated and cured together, improving efficiency compared to single-board handling.<\/p>\n

Flexible setup<\/strong>
Ideal for different PCB designs or low-volume orders, especially in \u30d7\u30ed\u30c8\u30bf\u30a4\u30d7PCB\u30a2\u30bb\u30f3\u30d6\u30ea<\/strong>.<\/p>\n

Lower equipment cost<\/strong>
Compared to fully automated inline systems used in high-speed SMT\u30a2\u30bb\u30f3\u30d6\u30ea<\/strong><\/a>, batch processes require less investment.<\/p>\n
