PCB DIP plug-in processing is a very important process in PCBA chip processing, and its processing quality directly affects the functional properties of , so it is necessary to pay more attention to the DIP plug-in process.
Pcb circuit board proofing: pcb circuit board proofing refers to the production of a small part of the product as a sample before the start of mass production, so that it can be better completed, and the perfect combination of mass production circuit boar
Suitable paper is used to print the design and transfer it to bakelite, we will use vinyl support paper for labels, another one that gets very good results is adhesive paper support.
PCBA three anti paint coating methods: 1, impregnation, 2, spraying, 3, brush coating, 4, selective coating
Why do PCBA circuit board inspection: PCBA inspection is a link in the whole production process of PCBA processing, is an important means to control product quality
With sufficient theoretical basis, more practice, more learning, more summary, in order to be qualified for the PCBA circuit board maintenance post.
PCB performance test is a necessary test to ensure the stability of product performance after processing. It is divided into different tests according to the actual environment and purpose of product use.
Three anti-paint, also known as PCBA electronic circuit board protective oil, the use of three anti-paint PCBA circuit board with waterproof, moisture, dust "three", cold and heat shock resistance, aging resistance, radiation resistance, salt sp...
PCBA is one of the basic components of electronic components, PCB it through surface assembly technology (SMT), and the whole process of DIP plug-in insertion, known as PCBA process.
PCBA test stand is an indispensable test tool in SMT patch processing and production. It mainly tests the produced circuit board, and determines whether the board is a good product by the detected signals, pictures, sound temperature and so on.
Precautions for applying three anti - paint:1, can not let the PCB circuit board surface dripping, fluid paint, semi-humid phenomenon, 2, should ensure that the three anti paint uniform, bright, smooth, 3, can not let the surface of the paint layer of pin
Measures to reduce the tin residue of PCBA tin beads: 1, attach importance to the production of steel mesh, combined with the specific component layout of PCBA board, appropriately adjust the size of the opening, so as to control the printing amount, 2, b
