Splet26. avg. 2024 · 1 Answer. Since there is an air gap (on DB9 the gap exists between the conductors on the back, on the pogo pins the gap exists between the pins) you would use … SpletClearance is the distance between objects from point to point, in 2D or 3D. The difference with a creepage check is that it considers the 3D path across the PCB. You can think of this as the terrain. Imagine a traveller walking between two villages.

SpletFor example: the pin to pin distance must 10mm but due to board space we can only achieve 8mm. We add a slot between the 2 pins, the "creepage distance" is now 12mm (shortest distance measured from pin to slot to pin). However the DRC is still present because CM does not know that we have the slot.

SpletPRINTED CIRCUIT BOARD (PCB) SPACING / CLEARANCE vs. VOLTAGE IPC-2221 is generally accepted in electronic industry as a generic PCB design standard. However, when it comes to distances between the PC traces, in my view, the IPC-2221 table 6-1 stepwise limits are mostly baseless: the curve for spacing vs. voltage should be linear. SpletCreepage and clearance distances Protection against electrical operating voltages Creep- and clearance distances To protect persons or system from the effects of electrical operating voltages, especially in the case of malfunction of equipment, sufficient measurement of the clearance and creepage distance is required.

Splet07. maj 2024 · Creepage is different. It is the spacing rule that is applied between two conductive elements over an insulating surface – the substrate. It turns out that this can be a very important factor when dealing with high-voltage applications on a PCB design. Creepage will always be equal to or greater that the clearance between two conductive …
