O Caso<\/h2>\n\n\n\n

Inspe\u00e7\u00e3o Precisa de Soldagem BGA<\/h3>\n\n\n\n

O encapsulamento Ball Grid Array (BGA) \u00e9 amplamente utilizado em projetos de semicondutores de alta densidade para melhorar a confiabilidade el\u00e9trica e minimizar curtos-circuitos. As conex\u00f5es el\u00e9tricas s\u00e3o formadas por uma matriz de esferas de solda na parte inferior do pacote, permitindo interconex\u00f5es compactas entre o BGA e a placa de circuito impresso (PCB).<\/p>\n\n\n\n

BGAs pl\u00e1sticos com substratos laminados s\u00e3o comuns na fabrica\u00e7\u00e3o em grande escala. Durante a soldagem por refluxo, o estresse t\u00e9rmico e a varia\u00e7\u00e3o de temperatura podem deformar o PCB ou o pacote, causando defeitos como n\u00e3o molhamento, sobreposi\u00e7\u00e3o de esferas de solda, juntas frias e vazios. Esses defeitos podem levar a curtos-circuitos ou reduzir a confiabilidade das conex\u00f5es, tornando a inspe\u00e7\u00e3o precisa da soldagem BGA cr\u00edtica.<\/p>\n<\/div>\n<\/div>\n <\/div><\/div>\n\n\n\n

\n
\n

O Desafio<\/h2>\n\n\n\n
\n

Inspecionando Juntas de Solda BGA Ocultas<\/h3>\n\n\n\n

A inspe\u00e7\u00e3o \u00f3ptica tradicional n\u00e3o consegue avaliar juntas de solda BGA localizadas sob o pacote. A inspe\u00e7\u00e3o por raios X \u00e9 necess\u00e1ria para detectar defeitos internos; contudo, imagens de raios X frequentemente apresentam baixo contraste e alto ru\u00eddo de fundo.<\/p>\n\n\n\n

Sistemas de inspe\u00e7\u00e3o baseados em regras enfrentam dificuldades nessas condi\u00e7\u00f5es. Varia\u00e7\u00f5es na forma e densidade da solda reduzem a confiabilidade da detec\u00e7\u00e3o e aumentam falsos positivos, limitando a efic\u00e1cia da inspe\u00e7\u00e3o em ambientes de produ\u00e7\u00e3o.<\/p>\n<\/div>\n<\/div>\n <\/div><\/div>\n\n\n\n

A Solu\u00e7\u00e3o<\/h2>\n\n\n\n
\n

Inspe\u00e7\u00e3o de Soldagem BGA com IA SolVision<\/h3>\n\n\n\n

O SolVision<\/a> utiliza aprendizado profundo<\/a> para analisar imagens de raios X na inspe\u00e7\u00e3o de soldagem BGA. O modelo de IA \u00e9 treinado com dados de defeitos rotulados, incluindo n\u00e3o molhamento, sobreposi\u00e7\u00e3o de esferas de solda, desvios de tamanho e curtos-circuitos.<\/p>\n\n\n\n

O modelo identifica padr\u00f5es sutis de defeitos em imagens com ru\u00eddo e baixo contraste que algoritmos tradicionais n\u00e3o conseguem detectar de forma confi\u00e1vel. Com o SolVision, a consist\u00eancia da inspe\u00e7\u00e3o melhora enquanto os falsos positivos s\u00e3o reduzidos, garantindo controle de qualidade inline est\u00e1vel.<\/p>\n<\/div>\n<\/div>\n <\/div><\/div>\n\n\n\n
