Key Production Processes for High Layer Count PCBs Average layer count has become one of the standard measures of a board shop’s technical level, and for good reason. High layer count PCBs are not simply thicker versions of a normal multilayer board. It combines more layers with thinner dielectric, denser…

Surface Mount Technology Advantages in Wireless Charging Board Production Surface mount technology is now the default method of building electronic hardware, and it is worth understanding why, because the reasons are not only about speed. Removing the drilled hole from the process changed the economics of assembly, the electrical behaviour…

PCB Rinse Water Conductivity Control: Reading the Rinse Rinse water looks like the simplest part of a wet process. It carries flux residue and process chemistry away from the board, then goes to drain. The conductivity reading tells you how much ionic material that water still holds. When the number…

SMT Assembly Line: Stage by Stage from Stencil to AOI An SMT line is a sequence of machines whose settings have to agree with one another and with the board being built. Following the flow stage by stage is useful not only for operators but for designers, because every station…

PCB Operator Certification Program: Process Details and Inspection Points Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB operator certification program from the perspective of a PCBA factory…

SMT Stencil Design and Aperture Requirements The stencil decides how much solder paste lands on every pad, and no amount of machine accuracy compensates for an aperture that is the wrong size or the wrong shape. Treating SMT stencil design as a manufacturing detail rather than part of the design…

PCB Conveyor Width Setup: A Practical Review for Manufacturing Teams Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB conveyor width setup gives you a practical…

PCB Fume Extraction Duct Design: What Matters on the Production Line Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB fume extraction duct design gives you…

PCB Depaneling Fixture Design: What Matters on the Production Line Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB depaneling fixture design gives you a practical…

PCB Solder Pallet Selection: What Matters on the Production Line Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB solder pallet selection gives you a practical…
