High temperatures of Pb-free assembly
in EventC-Alley is offering the services of global PCB assembly & manufacturing, PCB layout & design , reverse engineering. Few projects during PCB assembly may have below errors if designer do not pay attention to it. The PCB production cycle includes two main stages: fabrication of the PCB and assembly of components on the PCB. Variations in these processes are […]
It’s not ok to place components at the edge of a PCB (< 5mm)
in EventThe PCB traverses stations on the assembly line on a conveyor belt. This conveyor belt, which is located along (almost) the entire production line, is composed of two parallel tracks. These tracks comprise a small depression that enables the PCB’s stability on the conveyor belt. The projection of the depression’s area on the PCB is […]
How is it important for fiducial points.
in EventFiducials on the PCB are used as datum points that assist the machine head in pinpointing the precise location to place components. Correct locations and definitions of these markers during design have significant implications for assembly quality. Based on these markers, SMT machines carry out their precise actions, such as solder paste application, component placement, […]
BGA’s ability in design & assembly
in EventSince the solder paste layer is much thinner, we get the same advantages as the BGA package, but even more so; thermal resistance is even smaller, and inductance is even lower. For modern power-dense point of load modules, which can carry very high currents , thermal efficiency is more important than ever before; BGA’s […]
How can you tell different revisions of the same board?
in EventOne of the commonest requirements in project development is to see what has changed. You might want to look at the differences between two revisions of the same file, or the differences between two separate files. Over time most PCB designs need to change – a mistake is found, or a part becomes obsolete, etc. […]

Advance in PCB surface preparation
in EventRecently Europe and US (except for some mil spec and medical applications) resulted in development of lead-free (SAC) solders that are tin-based, with additions of silver and copper and with traces of bismuth, indium, zinc or antimony. Initially, the higher soldering liquidus temperature led engineers to specify high glass transition composite substrates (170°-180°C Tg) but careful […]
