Hello eveyone,
Please can you help me.
I am designing a plastic enclosure that houses a PCB which needs to pass an IPX4 test.
I am currently have problems when testing the enclosure that in that the walls I have created to prevent water ingress seem to be drawing water in to the moulding as a result of capiliary action. Therefore I was hoping that someone could give a key point/rules when desiging the overlapping walls which will prevent capiliary action from taking place.
To give you a quick idea the enclosure is approxiately 150 x 150 x 30mm in size and the walls I have currently designed have about 10mm of overlapp and a clearance of approxiamately 0.15mm.
Thanks for your help in advance.
