ACME PCB Assembly ready for RoHS 2

ACME PCB Assembly ready for RoHS 2

Directive 2011/65/EU entered into force on 21st 2011 and requires the Member States to transpose the provisions into their respective national law by 2nd January 2013. The RoHS 2 Directive is part of the European Union’s horizontal waste management legislation.

The RoHS 2 Directive is part of the European Union’s horizontal waste management legislation. As we know, the RoHS 1 Directive is for 2002/95/EC. On the restriction of the use of certain hazardous substances in electronic and electrical equipment (EEE). The Directive 2011/65/EU is reffed to as RoHS 2.

RoHS and REACH are two different acts with different scopes and objectives. When overlaps occur, the strongest restriction should be applied.

ACME PCB Assembly provides RoHS 2 Directive assembly service in Carson, California. and Our PCB Suppliers to ACME PCB Assembly conform with RoHS 2 Directive.

How do you know if RoHS 2 applies to your products? if your product not EEE, or out of scope, provisions of RoHS 2 don’t apply, you don’t need to worry about it. By the way, automated integrated circuit board and printed circuit board (bare board) testers, CNC lathes, bridge-type milling and drilling machines, metal forming presses, they all benefit from an exclusion. The list below is the EU RoHS 2 Directive Exemptions to RoHS 2

Made in CA

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.

Surface-mount technology requires knowing the entire process that it entails. Surface-mount technology has specific demands for the design process since you need to use special PCB tools. As soon as the design is ready, the manufacturer will always do the testing with a single board first.

The prototype we create for you will have the task of confirming that the fabrication based on that design is possible and error-free. Once you confirm that, the entire process is virtually pretty much automated, and requires minimal involvement.

Thanks to the automation process, SMT assembly minimizes the errors that may happen due to having human involvement. It helps secure the improved reliability and consistency of the PCB boards. Some other advantages that SMT ensures are:

  • Reduced size and weight – by soldering components directly on the board, the SMT saves plenty of room. That is how you can maintain the reliability and performance of a PCB while reducing its size and weight.
  • More components in a smaller space – it is not only about reducing the size, but SMT also enables us to put more elements in a restricted area. That is how these boards can perform better than their predecessors while keeping their compact design.
  • Money savings – if you don’t use the same amount of materials as before, the cost should be decreased, too. Additionally, there is no need to go through hole-drilling operations to mount components. Thanks to that, you can also lower the labor costs.

As usual, We keep additional capacity, shorter time-to-market and State-of-the-art manufacturing capabilities. Fuji NXT Surface Mount Technology (SMT) pick and place machine give us the capability to working on Surface Mount Technology (SMT) component package smaller than 01 005 which is 1/4 size of 0201 component.

Acme Circuit Boards Assembly starting doing electronics contract manufacturing for SMT assembly (SMTA) since year 1994. Manufacturing in Carson which is in 10 miles south of Los Angeles airport, CA. ISO 9001:2015 certified is a guarantee for all right process at EMS.


Why Consider Using Through Hole Printed Circuit Boards?

In the printed circuit board business, there are two primary ways to mount components onto the circuit board: through-hole mounting and surface mounting. Through-hole mounting is the older technology and requires the circuit board manufacturer to drill holes through the PCB and place leads into the holes. More recently, surface mounted technology has taken over the field.

Through-Hole Components

Through-hole components come in one of two types of leads, radial and axial. Axial through-hole components run along the axis of symmetry of the component while radial components protrude in parallel from the same surface on a board.

Components of Surface Mount Technology

When you look at any modern PCB design, you will see SMT technology in most instances. Surface mount technology (SMT) is the most commonly used technology today. These types of boards and components have very small or no leads at all as their primary purpose is to be soldered directly on the surface of a PCB during the design process. This method allows for components to be much smaller, allowing for greater density and better overall performance on a smaller circuit board.

With surface mounting offering so many benefits, why even consider through hole flex printed circuit boards?

The reason is that through hole mounting offers stronger mechanical bonds. This makes through hole flex printed circuit boards the better option for devices that are designed to undergo major stresses, like sudden accelerations, collisions, or extreme temperatures. This makes them worth considering for military, automotive, and extreme sports applications.

Yun Industrial Acme PCB Assembly is capable of two types of printed circuit board assembly services. They are full and partial turn-key services. Full turn-key covers all aspects of PCB fabrication and assembly, including manufacture of PCBs, parts procurement, quality inspections, and final PCB assembly.

Recycling Unused PCB

We will be discussing the issue of PCB recycling, if it’s even possible, how it is done and what can we do as electronics design engineers to create more recyclable PCBs. When we say PCB we are meaning a PCB without any components on it.  Most electronic devices found out there have their components sitting in a nice looking Printed Circuit Board or PCB.  Since electronic devices are in high demand, PCBs are everywhere. Making sure their materials can be collected and reused instead of just throwing them into a landfill would potentially be a smart and environmentally sensible move if performed properly.

Remember that large order of printed circuit boards you ordered? You thought it would be a good idea to have a surplus of parts on hand in case you needed to increase production of your product line. Unfortunately, that product got discontinued, so now you have a huge stash of PCBs taking up room in your warehouse and on your accounting books. It is time to trash them?

Not so fast! In many cases, printed circuit boards can be reworked and modified. Do you have another electronic or computerized product in the works? Then contact ACME PCB Assembly  we may be able to re-purpose your PCBs. Our workers are highly trained in de-soldering and re-soldering surface mounted electronic components. We have also invested in specialized equipment that can assist us in these efforts.


Yes and no, before coming to a final decision let’s first see what a PCB is made of. A PCB is basically a layered sandwich of copper and FR-4. FR-4 is a fiberglass with an epoxy resin that has the purpose of bonding the fiber together and as an adhesive, it is also flame resistant. Apart from that, you can also find tin and small traces of gold and silver.

Don’t throw out unused printed circuit boards.
