Hello to all We need to calculate the theoretical amount of solder (In the wave solder – THT components) that will be used for each board, so Is there formula to calculate THT solder volume? For example for SMD solder paste volume we use Greely formula to calculate the theoretical amount of solder paste. ie: Greely Formula Greely = (Alloy Specific Gravity x Flux Specific Gravity) / (Flux % x Alloy Specific Gravity )+ (Metal % x Flux Specific Gravity) Thank you Juliano Bettim Ribeiro DATACOM Engenharia de Processos Rua América, 1000, Bairro Industrial, Eldorado do Sul, RS - 92990-000 Telefone: +55 51 39333000 - Ramal 3484 Telefone Celular: +55 51 98446-2135 Fax: +55 51 39333003 site: <http://www.datacom.ind.br/> www.datacom.ind.br e-mail: <mailto:[log in to unmask]> [log in to unmask]
