One of the Gull-Wing (*) style components are called QFP components. It is a component from the Gull-Wing family of SMD components, other Gull-Wing family styles are SOT, SOD and SOIC components. The specific property of the QFP or Quad [...]
Printed Circuit Boards (PCBs) / PWBs (Printed Wiring Boards) are well known in electronics. The first printed circuit board, invented by Paul Eisler, dates back to 1936. At that time, the conductor tracks were drawn by hand and that was [...]
BTC-components are the “new generation” ICs that take up considerably less space than their “older” predecessors such as QFPs, SOICs, etc. BTCs (as the name suggests) do not have leads (legs) on the side of the component but metallized surfaces [...]
When handling ESD-sensitive products, grounding is the most important thing! This is possible using a wrist strap, ESD shoes, ESD safety clothing, etc. and this is common in the EPA (ESD Protected Area). What about ESD-safe gloves, are they [...]
A focus on the IPC-A-610 and IPC J-STD-001 Why this article? The IPC-A-610 and the IPC J-STD-001 are complementary standards, but each has its own purpose. However, it is not always clear to everyone what the specific uses of both [...]
Every advantage has its disadvantage In the new/latest revisions of the IPC-WHMA-620D Requirements and Acceptance for Cable and Wire Harness Assemblies and IPC-A-610H Acceptability of Electronic Assemblies the term TARGET and the pictures to this have disappeared. Advantage: The main [...]
Optimise your SMT-Reflow process and save on Rework and Repair Quite often I see operators in companies producing electronics perform repair or rework on printed circuit board assemblies that wouldn’t have been necessary if the reflow soldering process would have [...]
JBC is a major league player in the electronic interconnections industry, as it has been manufacturing soldering equipment and has built a global network for over 90 years. JBC not only offers one-stop shopping when it comes to soldering, but [...]
During the Repair and Rework, IPC-A-610 or IPC-7711/7721 training courses quite often we get the question which microscope or magnifier is most suited for the visual inspection of a printed circuit board assembly. An answer to this question is not [...]
IPC has published IPC-9121, Troubleshooting for Printed Board Fabrication Processes, an essential source of information for anyone involved in the fabrication or purchase of printed circuit boards (PCB's). This handbook covers over 650 PCB-process failures, with causes and corrective actions [...]
