... Preference for The answer to the lead-free problem could sound this simple: Immerse a printed circuit board into a solution, and the result is | CIRCUIT BOARDS PROTOTYPING | a final surface that can be stored and soldered. Completely level thanks to direct contact with the copper In fact, such a thing does exist: | CIRCUIT BOARDS PROTOTYPING | a lead-free alternative to HAL (Hot Air Levelling) with these wonderful features, at least from the point of view of the PCB manufacturer. OSP is | CIRCUIT BOARDS PROTOTYPING | an organic solution based on an imidazole substitute which, by means of dipping or rinsing can be selectively applied to the copper surfaces, ready for | CIRCUIT BOARDS PROTOTYPING | soldering. A transparent layer, max. 0.2 to 0.6 my thick, covers the copper like a barely visible clear varnish. Purely as a sealing agent, OSP | CIRCUIT BOARDS PROTOTYPING | offers good preconditions to adhere components that require an absolutely level surface, thanks to the fact that the soldering paste is applied directly to the | CIRCUIT BOARDS PROTOTYPING | copper. The common problem of twisted fine-pitch components due to raised “tin bubbles” on the HAL surface is, ...
