Providing Electronics Manufacturing Services (EMS) Since 1993

Local PCB Assembly house in LA.

The electronic manufacturing services (EMS) industry took off after the late 1970’s. Before this, most electronics manufacturing that was done in large quantity production runs was handled by in-house assembly only.

Now, the electronic manufacturing services (EMS) provider offers more flexibility and easier resources to deal with issues for smaller companies who doing limited runs.  An electronic manufacturing services (EMS) provider is able to specialize in large manufacturing, raw materials procurement, and resources.

ACME PCB Assembly

Since the early 1990’s, the development of Surface Mount Technology (SMT) on PCB has allowed for the rapid assembly of electronics, many electronic components switched to Surface Mount Technology (SMT) from Through hole components.  SMT components are making more and more small footage, more and more fine pitch, the equipment for SMT components are requiring more and more accuracy. For small businesses, it is a good idea to outsource your EMS needs.

Outsourcing all your manufacturing needs to a Electronic manufacturing services (EMS) provider helps you to save money, it also helps you to control your overhead cost, which in turn reduces your companies overhead cost.  As a result, Electronic manufacturing services (EMS) provider gives you the opportunity to produce your products at a lower cost.

ACME PCB Assembly in Carson, California has been an Electronic manufacturing services (EMS) provider since 1993. OEMs are realizing the benefits of outsourcing versus in-house manufacturing. Outsourcing to Electronic manufacturing services (EMS) provider enables OEMs to concentrate on their core competencies by allowing Electronic manufacturing services (EMS) providers to supply manufacturing expertise. The main benefits of outsourcing include a reduction in costs and investment, additional capacity, shorter time-to-market and state-of-the-art manufacturing capabilities.

As your Contract manufacturer, ACME circuit board assembly will become a business partner who has a vested interest in your success. By outsourcing to ACME circuit board assembly, ACME PCB Assembly strive to understand your ever-changing needs in your specific competitive markets. Our objective is to provide not only quality products with a competitive price but become a partner for our customer, from product design to the distribution process.

Common Terms for PCB Assembly Services

What the Heck Is Your PCB Vendor Talking About? – Common Terms for PCB Assembly

Every industry has its established lingo, which helps its members communicate more efficiently. If you are on the outside looking in, however, it can seem like they are speaking a foreign tongue. This becomes a problem when you need to work with vendors on ordering printed circuit boards for your device or your prototype. If you’ve gotten lost while trying to speak to your vendor (SMP, SME, SMD?), then you’ve come to the right place. Here is our no-nonsense guide on the most common terms in the printed circuit board industry:

  • PCB – Stands for Printed Circuit Board. Printed circuit boards are found in every single device that uses computing and data. PCBs act as the “highway” in transferring data between components within a device.
  • THM – Stands for Through-Hole Mounting (also known as Thru-Hole Mounting). THM is an older assembly technology that mounts components on a PCB by drilling holes through the PCB and placing component leads into them. This has largely been replaced by SMT assembly, though there are still some situations in which THM is preferred.
  • SMT – Stands for Surface Mount Technology. SMT was first introduced in the 1960s and rose to prominence in the 1980s. Today, it is the dominant form of PCB assembly. SMT does not require drilling holes through a printed circuit board. Its components are smaller than THM and can be placed on both sides of the PCB. This allows for a denser allotment of components and a more powerful PCB.
  • Substrate – The substrate is the actual board upon which wires and components are placed. It gives the PCB its structure and also insulates conductive parts. PCBs can be made from a variety of different substrates. All PCB substrates are non-conductive. Common substrate materials are: FR-4 (a fiberglass-epoxy laminate), Teflon, ceramics, specialized polymers
  • Traces – Traces are the things that electrically connect the connectors to the components. The most common material for the traces is copper. The copper layer of a PCB goes on top of the substrate. In double-sided PCBs, copper traces are placed on both sides of the PCB.
  • Soldermask – Have you ever wondered why almost all PCBs are green? This is the soldermask. This layer goes on top of the copper layer and functions to insulate the copper traces. It prevents the highly conductive copper traces from making contact with other metal components of the PCB.

While this is far from an exhaustive list of common terms used in the PCB industry, hopefully this guide will help you better understand and communicate with your printed circuit board manufacturer.
