O COB s\u00f3 pode ser descrito como um produto intermedi\u00e1rio entre as tecnologias atuais. Al\u00e9m disso, o CSP (chip scale package) deve ser o processo intermedi\u00e1rio do chip a bordo para o chip virado.<\/p><p>COB \u00e9 para transplantar a liga\u00e7\u00e3o de fio encapsulado de CI e opera\u00e7\u00f5es de c\u00e1psula para a placa de circuito. Em outras palavras, a matriz nua originalmente anexada \u00e0 estrutura de chumbo \u00e9 anexada ao PCB. Al\u00e9m disso, trocamos os fios da colagem \u00e0 estrutura do fio para a almofada de solda dourada da placa de circuito impresso, e depois usamos cola ep\u00f3xi para cobrir bolachas e fios ao inv\u00e9s da embalagem original do molde. O chip a bordo poderia salvar o processo de fabrica\u00e7\u00e3o da selagem e marca\u00e7\u00e3o do CI. Tamb\u00e9m pode reduzir o custo da gest\u00e3o e do pino da f\u00e1brica de selagem de CI, portanto, basicamente seu processo ser\u00e1 mais barato do que o processo de embalagem de CI.<\/p><p>Por ser barata, a tecnologia de chip on board era tipicamente usada apenas em produtos eletr\u00f4nicos de consumo de n\u00edvel inferior que eram menos confi\u00e1veis, como brinquedos, calculadoras, pequenos monitores e rel\u00f3gios, porque eram t\u00e3o baratos que voc\u00ea podia simplesmente jog\u00e1-los fora e comprar um novo. Portanto, o processo inicial de chip on board era em sua maioria OEM do tipo familiar, aberto pelos funcion\u00e1rios da f\u00e1brica de selagem de CI. A sala de estar era a f\u00e1brica, e n\u00e3o havia controle ambiental. Muitas vezes se confundia que a qualidade do chip a bordo era t\u00e3o pouco confi\u00e1vel.<\/p><p>Mas com o progresso dos tempos, h\u00e1 cada vez mais f\u00e1bricas grandes olhando para seu pequeno tamanho, assim como a tend\u00eancia de produtos finos e curtos, o uso do chip a bordo nos \u00faltimos anos tem sido uma tend\u00eancia cada vez mais difundida, tais como telefones celulares, c\u00e2meras fotogr\u00e1ficas e outros produtos curtos t\u00eam muitos produtos no processo do chip a bordo.<\/p><p>A COB tem outra vantagem que faz com que alguns fornecedores gostem particularmente dela.
