Tips & Tricks: Avoiding Solder Escape/Wick during Reflow

Avoiding Solder Escape/Wick during Reflow

Have you ever wondered why sometimes you have poor Solder joints on your PCB’s!

One of the main reasons is that the Solder Paste flows away from the pad on the PCB during Reflow, this is known as Solder Escape, Solder Wick or Solder Drainage.

Why does this happen, well there are a few reasons but inevitably they are all the result of Thermal Dissipation during the Reflow process. Basically, the heat flows away from the pad on the PCB to a larger Thermal conductive area that’s connected to the pad and unprotected by a Soldermask Dam, these include:

  • Via Holes
  • Copper Areas
  • Larger Tracks

Below is an example (animation) of a Via Hole that is too close to a SM pad and therefore has no Soldermask Dam to stop the Solder Paste escaping into the hole.

There are several solutions to this issue and Eurocircuits is developing a PCB Assembly Guideline to help Designers understand and creating PCB layouts that may create potential Assembly issues.

Please visit our PCB Assembly Guidelines section on Solder Escape/Wick for more information on how to avoid this issue.

Tips & Tricks – BOM & CPL Data

It has been over a year since we launched our Prototype & Small series Assembly service.

One question that we are often asked is, what information must you our customer supply for the Assemble service.

To answer this question, we need the BOM (Bill of Materials) and CPL (Component Placement List) data.

These files are usually generated by the CAD system and output in an ASCII format, the format varies from one CAD system to another however, it is the information contained within these files that is important.

The BOM must contain the information below:

  • MPN (Manufacturers Part Number) or Supplier Part Number.
  • Full Description of the Part (including value where applicable)
  • Component Reference Designations that use this Part.

Addition information that is also very useful:

  • Manufacturer
  • Supplier

Below is an example of a BOM file.

It is important that each line that contains a Component Reference Designator also contains the required part information.

Using the CPL we automatically superimpose the components listed in the BOM to the PCB, allowing the verify the component placement on the PCB.

The CPL file must contain the following information:

  • Component Reference Designator (e.g. C1, L2, R3 etc).
  • X and Y Position of the component Center.
  • Orientation
  • Side (Top or Bottom).

Great news for KiCAD and Eagle users as this information is already contained within the .BRD or .KiCAD file.

Below is an example of a CPL file.

For more information concern BOM and CPL files please visit the Eurocircuits PCBA Visualizer – user guide and the Eurocircuits Guide on How to Upload or Import BOM & CPL files into the PCBA Visualizer.

Eurocircuits Tips & Tricks – How to order the most cost effective PCB

What options are available to help reduce the cost of your Prototype PCB?

When uploading your PCB data to your Eurocircuits account you may have noticed on occasion some small Icons next to certain options:

  • Single coin, indicating this option has additional costs – Amending your design to fall into a classification which no longer has additional costs.
  • Stack of coins, this indicates that the option selected no longer falls into our pooling service and the cost will raise accordingly to reflect unique manufacture – here possible review the remarks and see if it is possible to amend the design to no longer fall outside of our pooling option, if this is not possible then use to the “customise matrix” to identify the most cost effective quantity.

In addition to the stack of coins your will also see a remark directing you to where the non-pooling option is:

We have worked to providing Design Rules which can be imported into 3 of the most popular CAD design packages. They will push your design to meet the cost effect design classification automatically, you can find these Design Rules here:

For “true” prototyping we also have the “NAKED Proto” service, by offering a high quality PCB which does not include soldermask or silk screen marking can reduce the price of you order by up to 45%.

Pooling customer orders and sharing the cost of production, the heart of our business and successfully offering affordable Prototype PCBs for 25 years.

Eurocircuits Tips & Tricks – Cost effective Solderpaste Printing

Eurocircuits Tips & Tricks – Cost effective Solderpaste Printing

Electronics is a very dynamic market, demanding smaller and smaller circuits, requiring very small tracks and gaps in the PCB layout. This also influences the components which can be used.

As Through Hole (THT) components are rarely available for these requirements, more designs are driven to SMD (surface mount devices). This causes additional costs to your small prototype series, namely no longer can you simply take a soldering Iron and solder wire to manufacture your boards. It is now essential to use Solderpaste and a Solderpaste stencil and printing device.

Solderpaste stencils can be expensive, requiring expensive machines to ensure perfect alignment for the stencil to the board.

Eurocircuits have worked with designers to understand what is required and how we can help to offer the right service for printing your boards with Solderpaste.

First we can offer Solderpaste stencils, you can order with a click of a button.

We also looked at our customers who need an alignment solution and for this we came up with the eC-registration:

Finally we thought long and hard and wanted to offer an affordable solution to align the stencil and boards accurately inside your lab environment. For this we can up with 2 solutions:

  • Stencil fix, see how this works here
  • Stencil-mate, see how this can help you here

Eurocircuits Tips & Tricks – Problem identification and Auto-Repair

We at Eurocircuits want to make your life as designers easier in any small way we can. You already have the stress and pressure of creating a practical and functional electronic design without the added pressure of knowing all the production restrictions and overcoming them before being able to have the peace of mind that you design can be made.

With our PCB Checker you can see not only the exact location of problem but also the measured values to allow you to either correct the technology specification or your design.

But did you know, we have continued to evolve our unique PCB Visualizer tool to automatically fix these problems for you too, saving you precious hours development time and stress.

Watch the 2 minute video below or read our short BLOG to see how you can save time on money getting your design produced.

Eurocircuits Tips & Tricks – Marking Editor

Eurocircuits tips & tricks – Marking Editor

Did you know that you could add your company logo to your PCB design, add text, Date code, UL marking or even determine where to locate your order number? Not only this but place them either in the copper layer or the silk legend layer?

But why would you do this? The answer is simple and opens a new world of possibilities and tools for design engineers. You can make your design more personalised by adding your company logo, what about adding your name to the board or easily marking it to identify a prototype and not production board? Add a QR code to the board to make it universally identifiable, Or how about simply specifying where your order number should be placed to ensure it is where you want and need it?

All of this has been made possible and easy to do through your PCB Visualizer, in just 3 minutes we can show you in the video below how to open a new world of PCB identification.

We have also create a short blog with more details to help you make the most of your Marking editor
