Protective varnish or filled with epoxy?

This question requires more detailed answer. In General it can be concluded that the protective varnish suitable for large surfaces of the plate, as well as those that include even a large number of items – mostly SMD – lutów or (in the case of the bottom side of the tile TNT and made in mixed technologies). In turn, the epoxy resin is ideal for pouring in full of small tiles that will work in extremely difficult conditions, although suitable also for sealing hard-to-reach nail areas like near connectors or high electrolytic capacitors MKP or MKT.

Protection from corrosion

Basic protection from the harmful effects of atmospheric gases and moisture provides a protective varnish PVB 16 (spray) or PVB 60 (a liquid applied with a brush). The spray is better suited to coating large surfaces with a uniform, aesthetic layer, in turn, a small brush will give much better control of the reach for an aerosol. If you own the PCB, and do not plan to use soldermaski, may be quite sufficient flux, LT-4, which in addition to the basic protection of copper, open on a different path, will also provide excellent lutowność panels – in particular when you're not using the service fields.

Repair contact fields in membrane keyboards

Of course, met repeatedly with "best practices adopted" or even damaged fields of contact information in the key fobs automotive remote controllers for equipment in broadcasting. These fields usually have several levels of intersecting ridges, which are closed using conductive rubber, is located under the right button, represent the easiest and cheapest type of microswitch. This solution is used in almost all trinkets for TVs, home theaters and air conditioners. To repair paths in places you can use a special protective lacquer based graphite company AG TermoPasty. This measure will also repair a low-power signal circuits printed circuit boards (when you should be aware of the relatively greater resistance of such compounds).
