Bagaimana cara mengetahui kapan alas meja anti-statis perlu diganti
Standar resistansi permukaan alas meja anti-statis di bengkel elektronik adalah antara pangkat 6 10 dan pangkat 9 10 ohm, dan hambatan permukaan bawah antara pangkat 3 10 dan pangkat 6 10 ohm, tetapi ketika alas meja anti-statis Ketika data deteksi hambatan permukaan lebih tinggi dari pangkat 9 dari 10, apakah berarti alas anti-statis telah gagal?
In fact, not necessarily, we have to learn to find the real reason why the resistance does not meet the standard, and avoid increasing the cost of replacing the pad. One possibility is that dust has accumulated on the surface layer of the table mat. Dirt and dust can hinder the conduction of static electricity. If it is, it is very convenient to handle. You can wipe it with clean water and then measure it. Another possibility is to check the anti-static work. Whether the table is grounded, test the volume resistance, if the data is not up to standard, you can replace the anti-static table pad.
