Al has been in the industry for over 35 years and has been with Epec for more than15 years. As field application engineer, he handles a wide range of responsibilities including reviewing PCB designs for manufacturability during the quoting and design stage, interacting with off-site manufacturing facilities to solve technical issues during production, and programming CNC machines for in-house projects, reworks, and modifications. Al’s technical expertise is essential to Epec’s engineering department and provides valuable insight when working with customers. Previous to working at Epec, Al spent 20 years with CPC Incorporated, a medium-sized PCB manufacturer, learning hands-on about PCB processing before moving into front end engineering. Al brings impressive expertise to Epec and has worked with over 50,000 different PCB designs from his start in 1981 to the present day. He works with Epec’s team to get all designs right ahead of time so that products will be correct the first time.

PCB Design Considerations for Tight Spacing

Written by Al Wright
Posted on September 14, 2017 at 10:00 AM

Printed circuit boards (PCBs) continue to shrink. As each generation of miniaturized components comes along, board designers find themselves able to work within ever-smaller PCB footprint sizes. While this is great news for consumers (compare the size of a 1994 portable phone to one of today’s models) it presents difficulties for fabricators.

PCB Layout Manufacturing Best Practices

Written by Al Wright
Posted on August 10, 2017 at 2:12 PM

As printed circuit board (PCB) designs have increased in complexity, they have both decreased in size and increased in density. Physical changed to circuit boards have forced PCB designers and manufacturers to develop new PCB layout strategies aimed at making full use of all available surface area.

Creating Standard PCB Fabrication Notes

When placing an order or requesting a quotation for printed circuit boards(PCB), it is extremely important to clearly state all of your requirements as completely as possible.

While this may seem obvious, it is surprisingly common for PCB fabricators to submit a pricing estimate to the customer based on information supplied within the request for quotation, only to receive additional information after pricing and delivery have already been agreed upon and a purchase order issued. If the new information affects the price and/or lead time, the fabricator must notify the customer of the changes in terms.

PCB Design For Manufacturability Analysis: Beyond DRC

Written by Al Wright

Your PCB design for manufacturing is critical to the success of your final application. Design features which make your board difficult to build add cost to your product, either by slowing down the production process, or by increasing the scrap rate.

Controlling PCB Costs: Part 2

PCB Laminate Utilization - Part and Panel Size:

In our first post on controlling PCB costs, we detailed many of the common cost drivers people face and ways to avoid them. For part 2 of controlling costs, we are focusing on one example that can cost a lot of dollars: PCB laminate costs and utilization

Printed circuit boards are run through the fabrication process in sheet form, typically with rows and columns of identical circuit boards or sub-panels on a single sheet, which are later cut out for shipment. One of the biggest potential cost adders in PCB manufacturing is that of a poor-yielding PCB or sub-panel. While this is true for even the least complex PCBs, it is especially true for multilayers.

Avoiding Expensive PCB Materials & Processes

Printed circuit boards are only one component of an enitre assembly designed to meet the best cost-to-performance ratio possible. The finished product into which the PCB is installed must meet a price point that compares favorably against competing products, so the lower the expenses, the more money your product returns. In order to make the best choices during the design cycle, it is important to first understand what drives the primary costs.

PCB Fabrication Data File Requirements

Written by Al Wright
Posted on September 17, 2014 at 12:08 PM

In order for Epec or any PCB fabrication company to quote your circuit boards accurately and with minimum delays, it's important to supply a complete PCB data file set, using industry-standard file types. Before you look at getting your quote, learn what information you need to supply to ensure a smooth PCB fabrication process.

PCB Wave Soldering And Minimum Pitch Distance

Written by Al Wright
Posted on August 7, 2014 at 2:46 PM

Wave soldering, the process of attaching electronic components to the printed circuit board (PCB), becomes increasingly difficult as pitch decreases. Pitch is the center-to-center spacing between the conductors on a PCB. So knowing that wave soldering becomes harder with lower pitch measurements, what is the minimum pitch distance you should maintain on circuit boards? With the appropriate controls, it is still possible to get a good result with pitches as low as 0.5mm (.0197"). Wave soldering defects can occur in pitches below 0.5mm, so we recommend this as the minimum pitch to wave solder a PCB.

Why Should You Fill or Plug A Circuit Board Via?

Written by Al Wright
Posted on June 20, 2014 at 2:53 PM

When it comes to printed circuit board manufacturing, there are a variety of PCB via process requirements to consider. Each has their own pros, cons, and cost adders so knowing these requirements can aid you when designing your circuit boards. In this post we will discuss the differences for why you would either fill or plug a circuit board via.

How to Select Proper PCB Copper Thickness

Written by Al Wright
Posted on December 31, 2013 at 1:40 PM

Selecting the optimal heavy copper thickness to apply to the plated through hole (PTH) plays a critical factor towards the overall reliability of the printed circuit board. There are two key elements to consider when determining optimal PCB copper thickness. The first is the current capacity of the barrel for acceptable heat rise. The second is the mechanical strength determined by the copper thickness, hole-size and whether or not there are any support vias.
