PCB manufacturability design and case study of the character, forma, assembly board (graphic combination, recommended) Diseño de PCB is complicated, and various unexpected factors can affect the overall solution. In order to produce high-quality PCB boards on time, without increasing design time and costly rework, design and circuit integrity issues must be identified early in the […]
We often meet various diffrent questions in design pcb, for instance, impedance matching or EMI rules. I’ve sorted some questions and answer about High-speed PCB, hope has some benefit to everybody. 1. How to calculate impedance matching issue at design high-speed PCB schematic layout? Impedance matching is among the vital factors in designing high-speed PCB […]
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 Diseño 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. Generalmente, 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 […]
In the soldadura de ondas 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? y, 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. Ahora, 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 […]
