Quality control process are critical for all aspects of circuit board and electronic device manufacturing processes to ensure compliance to design requirements, and accurate, reliable performance. Critical categories involve component, date and process. Components Start with design, selection, and coordination of component packages with PCBÂ layout footprints and Bill of Material (BOM) / Approved Vendor List […]

Optima Technology Associates, can offer production of your electronic product from inception to production, including hardware, software, management, applications. Such a total system solution can be difficult to find from other providers. There are many considerations to keep in mind when evaluating manufacturers for your custom projects. It may be helpful to review the various […]
Recent information from sources such as the IPC indicate that supply chain challenges remain a major problem for manufacturers and OEMs, but that the peak may have finally been passed. Lead times remain higher than in the past (pre-covid), updated economic data and responses from global electronics manufacturers finds that high material and labor costs […]
For wireless connectivity applications a fundamental decision that needs to be made, is whether to go with a standards based RF interface like Wi-Fi, Bluetooth, or ZigBee, or a proprietary RF design. There are many reasons and tradeoffs to consider, such as cost, security, power consumption, interoperability, design time, and certification requirements. Many of these […]
Wireless communication typically use radio waves to communicate over short distances of a few feet to longer distances of many miles (or even up to millions of miles for deep space radio communication). However, techniques also include optical, sonic and electromagnetic induction. Wireless communications involve numerous topologies. There are point-to-point devices using Bluetooth 3.0 and […]
It is commonly expected that there exists an inherent trust built into a solid supplier relationship that extends beyond the quality, price and delivery of your products. There is an expectation that the electronics manufacturer will keep your confidential information safe and secure. Even though it’s sometimes stated that Non-Disclosure Agreements, or NDA’s, are not worth the […]
It’s the goal of all SMT assembler to minimize all solder joint defects. Only through understanding of defect root causes, and their prevention can improvements in product quality be realized and sustained. The top three (3) assembly defects, accounting for up to three quarters of all defects (according to industry statistics) are solder opens, shorts […]
Reflow Profiles Solder paste composition defines the time/temperature or thermal profile required from a reflow process system. Therefore, as long as a specific solder paste is used, the required thermal profile will remain essentially the same. The EMS Assembly industry typically uses two types of standard reflow profiles—one for leaded solder assembly and the other for lead-free […]
Reflow Soldering Surface Mount Technology (SMT) and lead-free soldering have expanded the methods and techniques commonly used by EMS suppliers for reflow soldering. The main objective is to achieve maximum soldering of a large number of components while minimizing changeover times and to result with uniform, durable, and effective solder joints. Others include minimization of the stress […]
