We will continue to focus on customer satisfaction and become a trusted PCB service provider with \u201chigh quality\u201d and \u201cfast delivery\u201d.
Nossos produtos incluem PCB flex\u00edvel, PCB r\u00edgida, PCB r\u00edgida-flex\u00edvel e PCB HDI, Placa de circuito impresso de alta frequ\u00eancia<\/a>PCB de alta velocidade, PCB de metal, PCB de cer\u00e2mica e assim por diante, para atender \u00e0s necessidades dos clientes. Nossos produtos s\u00e3o amplamente utilizados em comunica\u00e7\u00e3o, equipamentos m\u00e9dicos, controle industrial, fonte de alimenta\u00e7\u00e3o, eletr\u00f4nicos de consumo, aeroespacial, ind\u00fastria automotiva e outros campos. Todos os nossos produtos s\u00e3o classificados como IPC e passaram pelas certifica\u00e7\u00f5es UL, ROHS e ISO9001.
Placas de circuito impresso flex\u00edveis, geralmente chamadas de FPCs ou PCBs flex\u00edveis<\/a>As placas de circuito impresso (PCBs) flex\u00edveis s\u00e3o uma grande inova\u00e7\u00e3o no campo da montagem e fabrica\u00e7\u00e3o de PCBs e desempenham um papel muito importante na fabrica\u00e7\u00e3o de produtos eletr\u00f4nicos. Nossas PCBs flex\u00edveis t\u00eam excelente estabilidade t\u00e9rmica, o que \u00e9 essencial para aplica\u00e7\u00f5es que exigem aten\u00e7\u00e3o \u00e0s varia\u00e7\u00f5es de temperatura. Elas podem suportar uma ampla gama de temperaturas sem afetar seu desempenho el\u00e9trico, mesmo em ambientes extremamente frios ou em ambientes de alta temperatura. As PCBs flex\u00edveis s\u00e3o menos propensas a falhas mec\u00e2nicas e, por isso, s\u00e3o adequadas para ambientes agressivos e aplica\u00e7\u00f5es que exigem movimentos frequentes.<\/p>\n\n\n

Precau\u00e7\u00f5es de revestimento de placas de circuito impresso flex\u00edveis<\/h2>\n\n\n\n

1, Pr\u00e9-tratamento de galvaniza\u00e7\u00e3o FPC<\/strong>
Ap\u00f3s o processo de revestimento, a superf\u00edcie do condutor de cobre \u00e9 suscet\u00edvel a adesivos, polui\u00e7\u00e3o por tinta e o processo de alta temperatura tamb\u00e9m pode provocar a descolora\u00e7\u00e3o por oxida\u00e7\u00e3o. Para obter um bom revestimento, \u00e9 necess\u00e1rio remover esses poluentes e a camada oxidada e limpar a superf\u00edcie do condutor. Como parte dos poluentes e do condutor de cobre est\u00e1 fortemente ligada, \u00e9 dif\u00edcil trabalhar com um agente de limpeza suave, por isso, muitas vezes, usa-se uma for\u00e7a espec\u00edfica de abrasivos alcalinos e o tratamento de moagem com escova. O processo de limpeza do pr\u00e9-tratamento tem um impacto significativo nas caracter\u00edsticas do FPC. Os fabricantes de PCBs precisam controlar rigorosamente esse v\u00ednculo para que o processo de revestimento subsequente estabele\u00e7a uma base s\u00f3lida.
2, Controle de espessura da camada de revestimento FPC<\/strong>
O processo de galvaniza\u00e7\u00e3o, a taxa de deposi\u00e7\u00e3o de metal de galvaniza\u00e7\u00e3o e a for\u00e7a do campo el\u00e9trico est\u00e3o intimamente ligados \u00e0 for\u00e7a do campo el\u00e9trico pela forma do padr\u00e3o do circuito e pela rela\u00e7\u00e3o da posi\u00e7\u00e3o do eletrodo. Na produ\u00e7\u00e3o dos fabricantes com base nos requisitos de design do produto, o controle preciso da espessura de diferentes partes da camada de revestimento, em geral, quanto mais estreito o fio, mais afiada a extremidade, mais pr\u00f3ximo do eletrodo, maior a intensidade do campo el\u00e9trico, a parte correspondente da camada de revestimento \u00e9 mais espessa. Para atender \u00e0s diversas exig\u00eancias dos produtos eletr\u00f4nicos quanto ao desempenho do FPC.
3\u3001Resposta da mancha de revestimento FPC<\/strong>
O revestimento de PCB rec\u00e9m-acabado pode aparecer, a solu\u00e7\u00e3o de enx\u00e1gue da superf\u00edcie n\u00e3o \u00e9 suficiente, a solu\u00e7\u00e3o de revestimento residual, ap\u00f3s um per\u00edodo de rea\u00e7\u00e3o qu\u00edmica lenta, a superf\u00edcie \u00e9 propensa a manchas, sujeira e descolora\u00e7\u00e3o, FPC flex\u00edvel devido \u00e0 textura do macio, desigual, a solu\u00e7\u00e3o \u00e9 f\u00e1cil de se acumular nas depress\u00f5es e reagir \u00e0 descolora\u00e7\u00e3o, para evitar essa situa\u00e7\u00e3o, devemos garantir que o processo adequado de enx\u00e1gue e secagem. Implementa\u00e7\u00e3o rigorosa das opera\u00e7\u00f5es relevantes no processo de produ\u00e7\u00e3o, para evitar defeitos de qualidade do produto devido a problemas de apar\u00eancia, melhorar a qualidade geral da imagem do produto e aumentar a competitividade do mercado.
4, Nivelamento de ar quente do FPC<\/strong>
Nivelamento por ar quente da tecnologia de revestimento de chumbo-estanho de PCB r\u00edgida, devido \u00e0 simplicidade de uso no FPC, a opera\u00e7\u00e3o \u00e9 mergulhar a placa de circuito verticalmente no banho de chumbo-estanho derretido ap\u00f3s o ar quente soprar o excesso de solda, mas as condi\u00e7\u00f5es do FPC s\u00e3o severas. Se voc\u00ea n\u00e3o tomar medidas, ser\u00e1 dif\u00edcil mergulhar a FPC na solda, ela precisar\u00e1 ser ensanduichada entre a opera\u00e7\u00e3o da placa de malha de a\u00e7o de tit\u00e2nio e a superf\u00edcie dever\u00e1 ser pr\u00e9-limpa e revestida com fluxo. Ao mesmo tempo, o nivelamento com ar quente \u00e9 f\u00e1cil de fazer a solda a partir da extremidade da camada de cobertura perfurada por baixo, especialmente quando a for\u00e7a de liga\u00e7\u00e3o \u00e9 baixa com mais frequ\u00eancia. O filme de poliimida absorve \u00e1gua com facilidade, e a evapora\u00e7\u00e3o da \u00e1gua durante o nivelamento com ar quente pode fazer com que a camada de cobertura fique com bolhas e descasque. No ar quente, o nivelamento deve fazer um bom trabalho de gerenciamento da umidade de secagem, seguir as especifica\u00e7\u00f5es de opera\u00e7\u00e3o para garantir o bom andamento do processo, reduzir a taxa de defeitos do produto, reduzir muitas barras e melhorar a efici\u00eancia da produ\u00e7\u00e3o.<\/p>\n\n\n
