Chekutanga pane zvese, isu tinofanirwa kuziva kuti mumutsara wekugadzira weSMT, iyootomatiki solder paste kudhinda muchinainoda kurongeka kwepamusoro, solder paste demoulding effect yakanaka, kudhinda kwacho kwakagadzikana, kwakakodzera kudhindwa kwe densely spaced components.Izvo zvisingabatsiri ndezvokuti mari yekugadzirisa yakakwira uye ruzivo rwevashandisi rwakakwirira.
1. Kana scraper yeSMT muchina wokudhindainofamba ichienda mberi pane imwe spidhi neAngle, inoburitsa kumwe kudzvinyirirwa pane solder paste, iyo inosundidzira solder paste kuti ikunguruke pamberi pe scraper uye kuburitsa kudzvanywa kunodiwa kupinza solder paste mumambure kana buri rinodonha;
2. Iyo adhesive friction force ye solder paste inokonzera shear ye solder paste panosangana scraper net plate yeSMT stencil printer.Simba rekugera rinoderedza viscosity ye solder paste, iyo inobatsira kune yakatsetseka jekiseni re solder paste mukuvhura kana kuvuza kwetemplate.Kune humwe hukama hunodzora pakati pekumhanya kweblade, blade pressure, blade Angle ine template, uye namira viscosity.Naizvozvo, kudhinda kwemhando ye solder paste inogona kuvimbiswa chete kana maparameter aya achidzorwa zvakanaka.
3. Kana blade ichienda mberi neimwe speed neAngle, butt paste inoburitsa imwe pressure, simudzira solder paste pamberi pe scraper roller, inoburitsa solder paste mumambure kuvhura (template) iyo inodiwa pressure, solder paste viscosity friction kuita solder. namatidza mune scraper uye sheet transfer shear kuvhura (template), shear simba rinoita kuti solder paste viscosity ideredze, nokudaro zvinobudirira kupinda mesh;Kana iyo scraper ichisiya kuvhurwa kwe template, iyo paste viscosity inokurumidza kudzokera kune yekutanga mamiriro.
Kana isu tichishanda, chete kana solder paste ichikunguruka pamberi pe scraper, inogona kuburitsa kudzvanywa kwekupinza solder paste mukuvhura;Kuwanda kwe solder paste kunotarirwa nedhigirii ye solder paste ichizadza kuvhurwa kwetemplate, uye kuvimbika kwedemoulding kunosarudza iyo solder paste leakage uye kuvimbika kweiyo solder paste pateni.
