Domestic PCB assembly houses are a much better alternative to foreign contract manufacturers. Domestic PCB assembly firms have a multitude of benefits.

• Key advantages include better quality assurance as well as the confidentiality of your intellectual property. Quality comes into question when outsourcing printed circuit board assembly as the firms located overseas may not have proper qualifications to handle your product. There is a growing problem of IPs being appropriated by non-legitimate organizations overseas, and one surefire way to minimize that risk is to find a trustworthy, reliable, and IPC A-610 certified company like ACME PCB Assembly to build your products.

• By outsourcing work overseas, one is typically trying to lower the cost of labor. However, lowering the cost of labor by outsourcing overseas can incur higher transportation costs. Outsourcing PCB assembly overseas is only viable in very few situations. A firm would need a product that has high volume runs with longer lead times and repeat jobs to even consider this method. Any other job, from prototyping to batch production, are better off done domestically as quality would remain the focus.

• Another advantage is that it would be significantly easier to communicate domestically as opposed to abroad. There are twenty-four time zones across the globe, and keeping track of which vendor or customer is in working hours could be a hassle to deal with. Language barriers are also an obstacle while outsourcing to businesses. Although many countries around the globe speak English, people with lower proficiencies could cause issues in communication and result in misunderstandings.

Flexible Circuit board

The electrical and thermal conductivity that copper creates makes it an obvious choice as a conductor in printed circuit board (PCB) construction, but in many applications that require flexible circuit boards, copper alloy metals can be far better to use. Some of those applications include using conditions of extreme heat or cold, where copper’s low resistance becomes a liability. Constantan is an alloy consisting of 55% copper and 45% nickel, this is one of several metals that has been proven effective for its higher resistance and lower thermal conductivity. Constantan used in flexible PCBs is an ideal choice for many applications.

Flexible circuit

Constantan is the oldest and most commonly used of what are known as “strain gauge alloys,” which are metals used to measure how materials react to stress from various forces. These alloys have become very important to the construction of many flexible circuits. Flex circuit boards are often designed for technologies that operate in harsh environments and require a high density of circuitry in enclosures with limited space. The market demand for flex PCBs that can withstand high temperatures has increased as such components are routinely used in oil drilling, semiconductor processing, medical diagnostic technology, and the construction of airplanes and defense systems.

Flexible circuits are small and light when compared with rigid PCBs and cable bundles. Flex circuits fit into many tight spaces, they can also bend around corners, and can better withstand vibration, high pressure, and extreme temperatures. They take up 75% less space than rigid PCBs and can be designed to accept virtually any necessary connectors. This makes flexible circuit boards ideal for many defense, medical, and aerospace technologies, like cryogenics, infrared imaging, and the construction of satellites, which often must withstand temperatures down to -150°F and up to 550°F.

Flex circuits can be printed single- or double-sided, multi-layer, or in combinations of rigid and flexible boards. All require unique processing in their fabrication. The choice for many designs includes thin, durable, material like Constantan in flexible PCBs. Constantan’s resistance remains stable across an extreme range of temperatures as well as in high pressure and other stressful situations. These qualities, plus its relatively low cost, have made Constantan foil a desirable conductive material for flex PCBs designed for hostile operating environments and rugged electronics.

In addition to solving the problem of thermal conductivity due to extreme external temperatures, Constantan in flexible PCBs can help maintain long-term reliability in situations when internal temperatures remain high. As electronics become faster and smaller, they require innovative designs and materials to deal with heat buildup. Along with the effective design of heat sinks and air flows, the use of Constantan as a conductor can lower thermal conductivity in flexible PCBs.

Many reasons drive the global push to “go green”. While nature conservation is one of them, ensuring economic and social wellbeing, mental and physical health, and a sustainable future for humans are some other powerful incentives.

This reliance on natural resources for material and energy requirement is becoming a major environmental and economic problem says EcoWatch, depleting resources needed to “power economies and lift people out of poverty.” Since many of the resources are non-renewable, at current rates of use, the world will run out of many necessary materials. Even renewable resources are at risk as some need long periods to be replenished point out by the experts.

Declaration of Conflict-Free Metal

Acme PCB Assembly hereby declares that the metal used in our production line is Conflict-Free

Acme PCB Assembly had investigated and will continue to monitor our supply chain to ensure that metal such as gold(Au), Tungsten(W), Tantalum(Ta), cobalt(Co), and Tin(Sn) are not derived or sourced from mines in conflict areas of the Democratic Republic of Congo, or exported through illegal means or trade routes that are controlled by non-governmental military group, unlawful military factions.

As Yun Industrial Co., Ltd. dba: Acme PCB Assembly registered in the united States of America, the trade routes that are considered “Non Conflict Free” include direct export from Congo, as well as exports through Rwanda, Burundi, Uganda, Tanzania, and Kenya. (metal exports from these countries are deemed by U.N. Security Council as part of Democratic Republic of Congo- mined minerals.)

We hereby confirm that the metals used in our products are ” Democratic Republic of Congo Conflict-Free”

We seek to be a valued partner to our customers by continuously striving to provide superior quality products and services with on-time delivery at very competitive prices.

As a full-service contract electronics manufacturer of both surface mount (SMT) and thru-hole (PTH) assembly, to support our mission, we continually acquire state-of-the art equipment to assure that we have the best resources to meet all of your PCB assembly requirements.

Wesley Dwelly – Dec. 2019

Printed Circuit Board FabricationI am the CTO at VAWD APPLIED SCIENCE & TECHNOLOGY. We have worked with ACME PCB on several projects. The PCB’s include, thru-hole and surface mount components ranging from power connectors to high density FPGAs with large pin count BGAs along with very fine pitch connectors and QFN’s. Their work has always been high quality and flawless. ACME is more like a design partner than an assembly house. ACME performs a detailed pre-assembly inspection that has saved us lots of money and time by finding footprint and part number issues that would have created costly rework or even scraping the PCB’s. This partnership is critical for efficient circuit board development and we highly recommend ACME PCB for even the most complex designs.

Timothy Jones – Oct. 2019

ACME recently built 25 sets of 3 different board designs for me. All were lead free. One had surface mount components on both sides. Some components were fine pitch QFN packages. ACME also supplied the PCBs from our original design files. This was our first post prototype production. The result was zero defects and zero problems of any note. On top of that, Stephen, Alice, and others at ACME were pleasant to deal with, timely, and very responsive. I sincerely appreciate your high-quality service. Thank you very much.

Reid Harrison – July 2019

I have used Acme for over four years, and they have done outstanding work for us on challenging projects. Their technical ability and quality control are top notch, and they really take the time to respond to customers’ needs. Very professional, and high-quality work with no missed deadlines, in my experience.
