We can reflow solder Printed Circuit Boards Assemblies (PCBA’s) by using convection ovens, infrared ovens but also with the aid of vapor-phase ovens. We see them quite often at companies that build prototypes or produce a lot of different [...]
The IPC J-STD-001 is increasingly required in contracts worldwide and as a result the demand for certification is increasing. And this is not just because the defence-industry is running at full power, but also because more and more electronics producing [...]
The name “no clean flux”, “low solids flux”, or “low activated flux” suggests that these flux residues do not need to be removed because they are harmless to the end product. However, this is not quite correct! No-clean flux [...]
Measuring is Knowing. Guessing is Missing. Measure the temperature profiles and other variables of your reflowsoldering, wavesoldering, vapour-phase-soldering- and rework & repair processes. This can be accomplished quite easily with the Smart Profiler SuperM.O.L.E.® Gold 2 from ECD or [...]
Solder mask, sometimes also referred to as solder stop mask or solder resist, is a thin layer of polymer that is usually applied to the copper traces of a printed circuit board (PCB). This layer of lacquer serves to [...]
Selective soldering has been on the rise in recent years. Sometimes the selective soldering system completely replaces the wave solder machine. Ersa-ECOSELECT-1 More and more we see that 80% or even more of the components used are [...]
Nowadays almost all electronic products are soldered fully automatically. This is possible with soldering machines such as: wave soldering machines, reflow ovens, selective soldering, pin-in-paste soldering, vapor phase soldering, laser soldering, soldering robots, etc. In this article we describe the [...]
If we talk about bare board (or PCB) manufacturing 2 IPC documents are commonly used. The one that is best known throughout the electronics industry is the IPC-A-600. The A in the designation tells us that these are Acceptance Criteria, [...]
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 [...]
