High quality of PCB design or layout will take much convenience to PCB fabrication & manufacturing process, and improve the ratability of the SMT assembly process The guidelines shown here are focused in a few key points that will help you with routing, manufacturability, basic signal integrity, and PCB assembly. 1. The spacing size between … Continued
PCB surface finishing technology When surface finish (also called surface coating) defined to a PCB it means an intermetallic joint between the exposed bare copper of the solder-able area of the circuit board and the electronic components, this excluding the area of solder mask. Printed circuit boards without a protective coating would be susceptible to … Continued
Specifically, both specification of the IPC-A-6012 and the IPC-A-600 are guiding documents made for the bare printed circuit boards. IPC-A-600: is a specification and document for the inspection criteria of PCB, which is a the visual representation of the IPC-A-6012 document. IPC-A-6012: is a guiding document for the PCB manufacturing process. IPC-A-610: is a guiding document for the acceptability of … Continued
A conformal coating is a type of thin polymeric film applied to a PCB (printed circuit board) by machine or by manual in order to have the electronic PCB boards and its components to be protected from the environment and corrosion. Normally, the film is applied at typical thickness of 25-250µm and ‘conforms’ to the shape of … Continued
When it comes to talk about PCBs (printed circuit boards), nearly it is impossible to get a fixed answer that how many layers you can have. Some IC test mainboards even have nearly a hundred layers in their construction; but, the most consuming electronic products only have common layered PCBs usually from two to four … Continued
Weller Technology’s mechanical assembly work initially consisted of adding low-mid volume items such as brackets & panels to the printed circuit board assemblies that we manufactured. At Weller we have the necessary equipment, technicians and machinists to accommodate the most complex and costumed assemblies. Customer can expect convenience and collaboration as their order is processed, … Continued
Within any simple electronic devices we used nowadays, there is a PCB (printed circuit board) drive it to run. The PCB is the core component of the electronic devices, whether it is a consume product such as battery charger, the communication equipment such as mobile phone, or transportation tool such as vehicle, even it is … Continued
What is the heavy copper PCB Usually, when out-layers or inner-layers of any printed circuit board are specified to use ≥2oz base copper foil, we call it heavy copper PCB (or thick copper PCB board). For final finished copper thickness (means base copper + plating copper) we normally follow customers’ requirements to do.But,if no specific … Continued
Optimize the global manufacturing cost of PCB and PCBA prototypes When it comes to start a PCB design for prototypes, Most circuit board designers like to put various PCBs (the same layer count and stack up but with difference in size, shape etc) into one panel to optimize the cost in the PCB fabrication and … Continued
