1.Laminate cutting (CUT) Cutting is the process of cutting raw CCL(Copper-clad laminate) into boards that can be made on the production line First, let’s explain a few concepts. a) UNIT: Refers to the Conception de PCB engineers to design the unit graphics. b) SET: Refers to the engineer to improve production efficiency, facilitate production and other […]
From PCB design to all the components soldered to complete a high-quality circuit board, requires PCB engineers, soldering technology, soldering workers and many other aspects of control. En général, people who are engaged in circuit design rarely solder circuit boards themselves, so they do not have extensive soldering experience. And the workers in the soldering factory […]
Many PCB manufacturers have huge competition with each other nowadays so parts suppliers insist on costs down under strong survival pressure. The situation could lead to a bad result, that is some suppliers tilt to purchase more cheap materials to replace good quality materials. Cheap means bad quality and lower cost, but hidden huge hazards […]
Dans le soudure d'onde process of PCB Assembly, although the residual tin bead on the circuit board is not the most serious disadvantage, it is a time bomb with the most unstable quality. The generation of tin beads should be generated when the printed circuit board leaves the liquid solder surface. Although there are many […]
1. What is PCB warpage? et, What is warpage standard? Board warped refers to the bending of a flat PCB board, also known as warpage. Serious warpage is a bit like an arch. PCB isn’t 100% flated at the actual manufacturing. We can judge the warpage degree of PCB by “warpage degree”. According to IPS […]
An unusual scene happened at the SMT workshop on 26th July, that’s dedicated channel had opened that is prepared for big equipment installed. Downstair is now lifting a new high-speed mount machine to this channel. A worker is an adjustment lifter carefully and that try pulls the big stuff into the workshop. We can watch […]
SMT factories have an important quality assessment index for production, which is First Pass Yield(FPY). FPY meaning is from beginning production to end process first pass ratio. The parameter reflects on manufacturing and quality control capacity of SMT factory, FPY higher, relative capacity higher. Maintenant, this industry pursues an aim is less than 100 ppm, […]
Recently, we passed CB Certification through hard work. We reckoned this is worthwhile spending this time and other sources, for customer and our company development. The aim of CB Certification is to help companies gain quick access to the world market, save our company from multiple audits, acquire certificates recognized by various countries from one […]
Many friends don’t know much about what’s the first article inspection(FAI) dans PCBA traitement. Suivant, I will introduce the FAI process of PCBA processing in detail. The production of the first piece of PCBA processing is because the previous process and equipment are not as mature as they are now, and the factory often has […]
With this covid pandemic, the economic circumstances are be changed, this is shocked many industries and businesses. Many people could be discouraged or even abandoned, but we still hold the line and fight for ourselves and the company.
