PCB production Steps
in EventPCB Etching Process All PCB’s are made by bonding a layer of copper over the entire substrate, sometimes on both sides. Etching process has to be done to remove unnecessary copper after applying a temporary mask, leaving only the desired copper traces. Though there are many methods available for etching, the most common method used […]

Why the etch pads are not big enough for vias
in EventNow C-Alley is using the leading edge technologies such as ball-grid arrays (BGAs), chip scale packaging, flip chips, QFNs, DFNs, and others. It shines x-ray radiation through a component package like a BGA to view images including wire bonding, solder joints, and solder defects, if any. Standard x-ray inspection is used for simple applications, whereas high-end […]
De-soldering components (through-hole and SMD)
in EventSMT parts have many advantages over their older through hole ancestors, namely: smaller size, lower cost manufacturing costs, and less likelihood of obsolescence. However, an often overlooked advantage is the ease at which surface mount components can be soldered and desoldered. At first this might seem like a controversial subject, but it isn’t to engineers […]

Printed circuit board sales on 2016
in EventTaiwan is considered the top-producing country for circuit board production (including manufacturing from China). Monthly shipments of printed circuits from Taiwanese manufacturers increased for both second and third quarters. Most of this increase was from the robust sales of PCs. New products from Apple dramatically increased the sales of flexible circuits until the month of […]
Reflow oven temperature during SMT production assembly
in EventSMT production assembly involves heating the PCB in a reflow oven. Oven temperatures are high, ranging to about 260°C. This heat spreads over the surface of the PCB. In the event thermal imbalance exists, such that during the soldering, substantial temperature differences are generated between two points on the PCB’s surface (ΔT) (more than 7°C), […]
