O objectivo desta Tese/Dissertação é conceber um sistema para a BOSCH
Termotecnologia S.A., na qual exerço as funções de Engenheiro de Qualidade de
Fornecedores de peças electrónicas, que permita testar funcionalmente dois tipos de
PCBA (Printed Circuit Board Assembled) utilizados em dois modelos de esquentador
estanque com denominação Celsius e Celsius Plus, produzidos nesta empresa para
mercados de todo o Mundo. Os PCBA foram desenvolvidos internamente pelo
departamento de ENG (Departamento de Desenvolvimento) e são actualmente
peças de compra cujo fornecedor está localizado na China.
Em primeiro lugar foi efectuado um estudo das necessidades da empresa
relativamente aos projectos necessários para melhorar os processos de investigação
de falhas e melhoria de Qualidade dos fornecedores de peças electrónicas, no
contexto do departamento onde este projecto se insere. A conclusão chegada foi
que existe uma grande necessidade de investigar avarias nas PCBA de compra do
fornecedor asiático de forma rápida e precisa, de modo a que seja possível trabalhar
mais activamente e rapidamente na melhoria de Qualidade do mesmo, melhorando,
por exemplo, os seus processos produtivos.
Em segundo lugar concebeu-se a solução a realizar. Optou-se por um conjunto
hardware e software desenvolvido de raiz, que inclui um jig (gabarit anti-erro – Poke
Yoke) dotado de agulhas para o teste FCT (Functional Circuit Test), um hardware de
aquisição de dados analógicos e digitais adquirido para o projecto, um hardware de
interface entre o PC (Personal Computer) e o hardware de aquisição de dados, e um
software desenvolvido em LabVIEW versão 8.6 (Laboratory Virtual Instruments
Engineering Workbench).
The target of this Thesis/Dissertation is to develop for BOSCH Termotecnologia S.A., company where I am a Supplier Quality Engineer for electronic parts, a system capable of testing the functionality of two PCBA (Printed Circuit Board Assembled) used in two room sealed water heaters named Celsius and Celsius Plus, produced by BOSCH Termotecnologia S.A. for worldwide markets. The PCBAs were developed by ENG (Research and Development department) and currently these parts are being produced in a supplier with factory located in China. At first all company needs were evaluated concerning the projects that could be implemented for failure investigation and supplier quality improvement in respect to electronic boards. It was reached the conclusion that we needed a quick and precise failure investigation on the PCBAs supplied by this Chinese supplier in order to promptly react and actively work with the supplier in quality improvement of their production process and product. In second place the application was designed and implemented. For that it was designed and developed a hardware and software, which includes a full-proof jig with a Poke Yoke design, test needles for the FCT (Functional Circuit Test), analog and digital data acquisition hardware, an interface hardware between the computer and the data acquisition hardware and a software developed using LabVIEW version 8.6 (Laboratory Virtual Instruments Engineering Workbench).
