Delays in your printed circuit board fabrication can be costly and time-consuming.  In today’s world, they are a commodity that there is never enough of.  Believe it or not, there are steps you can take to avoid those dreaded delays during your fabrication process.  We are going to discuss how you can take an active role in ensuring your printed circuit board fabrication runs smoothly and on schedule.

 

Communication

Follow up is an extremely important factor during the fabrication process.  Placing your project at the top of your “things to do list” is a must.  If you are communicating with your fabricator through email, or phone, you must be sure to answer any messages left in a timely manner.  Not answering them promptly can cause an interruption of the manufacturing, especially if a question is being asked or your guidance is needed.

 

Identify Long Lead-Time Parts

You may not realize it, however, some of the parts that are necessary for your project may take up to six months or longer to receive.  Working closely with your manufacturer as soon as you can will help them determine what they order and how quickly they can get it.  Printed circuit board manufacturing is not like shopping at your favorite grocery store, they will not always have the products in stock.

Correct Documentation

You should always keep your product documentation up to date with the correct information.  Speaking with the manufacturer candidly to find out what their specific requirements are is the best way to understand what they need, this way there will not be any confusion.  This will also help eliminate any unnecessary mistakes that will inevitably cause delays in the manufacturing process.

Product Demand Information

Never wait until you are out of (or almost out of) your product.  This only increases stress, time, and cost.  The cost of shipping overnight is much higher than normal shipping methods.  Come up with a way to order your supplies before you run out to avoid additional cost, stress, and time.

Consider a Domestic Manufacturer

Although the cost may be less expensive, you may end up paying a higher cost in the end.  You want to consider the following;

  • Shipping prices will be higher with overseas manufacturers
  • Communication may become more difficult due to time differences
  • The difference in time may also result in the delay of delivery

Find a Manufacturer Who Can Handle the Entire

Manufacturing Process

A manufacturer who can provide their services from start to finish is the most beneficial option for your project.  This saves time because it cuts down on the amount of time it takes to get from one manufacturer to another, be worked on, and then shipped back to the original fabricator.  It makes smarter business sense to keep your product in one place from beginning to end so it can be shipped directly to you.  It also will stop the “blame game” if something is defective you know who is responsible.

New High-Density, Direct Connection for PCB’s

Written by Admin on . Posted in PCB, PCB Manufacturing

A new high-density direct connection for printed circuit boards has been placed on the market by Phoenix Contact.  Dubbed the SDDC 1.5 connection system it offers four to thirty-two conductors using “SKEDD” plug-ins.  Using the SDDC 1.5 eliminates the need for a header and soldering during the manufacturing process, saving money.   Using a push-in spring connection allows wires to be terminated to the connector.  It has also been designed with solid, stranded wires that include a ferrule which can be pushed into the terminal block while the spring clamp stays closed.  Removing the wires is simple by pressing the orange spring lever with a regular screwdriver.  It has a range of 3.5-mm centerline and works with 24 to 16 AWG wires, can handle currents up to 8 A at 300 V UL, and provides the push-in spring connection.  Its double row design is the latest in SKEDD Technology that uses a gas-tight connection.

The SDDC 1.5 connection system’s contact zone consists of two flexible parts that allow contacts to be easily adjusted with the use of plated through-holes on the printed circuit board.  The good news for manufacturer’s is that the design is so easy, it will not add to the cost of manufacturing, in fact, it can save on the production costs.  When inserted there is enough force that will create a gas-tight connection, requiring nothing special for the PCB.  The connection stability of the board is achieved by locking pins that expand with the push of the orange locking tabs.  It can potentially be used in building automation, HVAC systems, elevators and escalators, and white goods.

Features include;

  • Allows you to save time during wire termination with its push-in connection
  • There is no need for a plug and header combination with its direct plug-in onto the PCB
  • Cost effective, only one component is necessary
  • Free positioning
  • Secure locking
  • Up to 25 mating and unmating cycles, for easy replacement
  • Intuitive use through color coded actuation lever
  • Quick and convenient testing using integrated test option

The SDDC 1.5 connection system is the newest high-density direct connection for printed circuit boards, that reduces manufacturing costs while allowing free positioning on the printed circuit board.  This is good news for the early adopters of this connection system, the implementation process does not require additional parts, the opposite is true, it only requires one component, does not require soldering and can be manufactured without using any tools.  Adding the integrated test option is simply another reason for considering the use of this connection system when necessary.

Why it is Necessary to Control Humidity in PCB Assemblies

Written by Admin on . Posted in PCB Assembly and component

Pcb Assembly humidity

A Printed circuit board is quite literally an insulated board on which wire is laid to create a circuit. They are a critical and very necessary part of all electronic products. They are in everything from complex computers to basic smartphones. Since they are the base for the circuits that transfer electricity, if they were not included in an average electric machine that machine would just not work not to mention the fact that there would be no place to put the components. The market for PCBs is currently at $60 Billion, that’s Billion with a “B” and growing.
Just like any other electronics, require careful conditions during production to ensure that the integrity of the board is maintained before shipping. In general, things like dust, heat, and the focus of this article, humidity, will have an effect on the PCB.

Just like dust can interfere with and even interrupt circuits, and heat can cause some metal within the circuits to melt, humidity, meaning the amount of moisture in the air, can allow current to run through unwanted areas of the circuit board, causing extreme damage to the board and the circuits on it. Although that should be enough to prove that control over humidity, there are additional factors that could be hazardous to the board, and, by extension, the equipment that it is a part of. Imagine if an expensive new desktop computer fell apart, or in a more extreme example, a computer-guided car or airplane failed mid-transit.
Too much moisture in the board can cause numerous problems from delamination to solderability issues. It is a very simple fact that moisture is not good for any electronic component and this is especially true when it comes to PCBs. Reality is that PCBs are extremely absorbent so both the builder and the end user must use extreme caution when avoiding moisture.
If you are an end user in a high humidity state such as Florida it is highly recommended that you pre-bake the boards before you solder them. Yes, the fabricator will have packed them with desiccant packs to keep the moisture down. But even the short time that the boards are exposed to humidity before they are put into the assembly process can be enough for that board to absorb too much moisture.
The most recommended way of keeping your products safe is to keep a humidity level at around %50, or between %40-%60, which will let the PCBs stay dry while not drying out completely or causing static discharge, which can occur below this level of humidity: a normal amount of moisture in the air only will not affect them.
Remember moisture is our enemy. But baking the moisture out the boards prior to the assembly process is the simplest and most cost-effective way to keep your boards safe and dry.
