Heavy Copper PCB Manufacturing From 3oz to 6oz Power modules, industrial drives, energy storage and automotive systems all carry currents that a conventional board with one ounce of copper cannot handle. Increasing the thickness of the copper is the direct answer: for the same width of trace, more copper means…

SMT Capacity: Daily and Monthly Output Once a product moves into volume, the scale of the assembly operation stops being a background detail and becomes the thing that decides whether orders are delivered and whether a busy season can be absorbed. Our SMT factory occupies fifteen thousand square metres and…

Design Deliverables From a Turnkey Development Project When a customer asks a development company to build a product, one of the first questions is what will actually be handed over at the end. The answer decides whether the product can be manufactured independently, whether it can be developed further, and…

EMC Design From the Layout Stage Many products discover that they do not pass electromagnetic compatibility testing late in development, and the correction takes several rounds, costs money and moves the launch date. The root of the problem is usually already present in the board, because a shield added over…

BOM Optimization Methods That Reduce Material Cost Most of a product’s material cost is fixed while it is being designed, and the scope for reducing it later through purchasing is limited. Teams often focus on whether the function can be implemented and leave the cost of the bill of materials…

Impedance Control in PCB Manufacturing and TDR Testing As signal rates rise, the characteristic impedance of a trace stops being an incidental property and becomes a requirement. When the impedance along a path is not what the design intended, the signal reflects at the transition, rings, and closes the eye…

Expedited SMT Service with 24-Hour Turnaround Product development runs to a calendar in which a day matters. A prototype that is verified a day later moves the launch date, and projects are frequently stuck waiting for a handful of assembled boards. What those projects need is not a promise to…

Odd-Shaped Panel Design for Game Controller Boards A game controller board is shaped by the shell, the buttons and the way the product is held, so curved edges, narrow necks and asymmetric outlines are normal. The board also carries a main controller, a wireless module, a crystal, connectors and the…

LGA Soldering and RF Test on a Positioning Terminal Board A positioning terminal board may start up and communicate normally and still take too long to acquire satellites, receive a weak signal or report an unstable position. Taking the module off the board at that point is a common reaction…

Moisture Sensitive Device Management for Meter Boards A smart meter communication board carries a main controller, a wireless module, memory, isolation devices and power conversion, and a proportion of the soldering problems that appear on such a board do not originate in the reflow oven at all. When an integrated…
