FAQ's

What does conductive pen do?

Conductive ink pens are specialized writing tools designed to draw circuits and create electrical connections on various surfaces. The ink used in these pens contains conductive materials (e.g. silver), which allow it to conduct electricity. Here's what a conductive pen can do: Circuit Prototyping: Conductive pens are often used for rapid prototyping of electronic circuits. Instead of traditional methods like soldering, engineers can draw circuit traces directly onto a PCB using the conductive pen. Repairs: These pens are useful for repairing damaged or broken circuit traces on electronic devices or printed circuit boards (PCBs). By drawing a new conductive trace with the pen, one can restore the electrical connection without requiring complex rework. Low-voltage Electronics: Conductive pens are suitable for low-voltage applications, such as wearable electronics, simple sensors, touch-sensitive interfaces, and other electronic projects that don't involve high power or high-frequency signals.

How do I patch the conformal coating after a PCB repair?

Chemtronics offers CircuitWorks Overcoat Pens in a variety of colors to match the PCB resist. Overcoat pens are basically acrylic conformal coating in convenient packaging, and the clear version can be used to coat small areas. Simply press down the pen tip and squeeze the barrel to dispense the coating material. 

Why is solder mask / resist / overcoat green?

Printed circuit boards (PCB) come in a variety of colors, including green, blue, red, brown, and even purple. The most common is green, but that can vary by application, industry, and the age of the PCB. Fashions change over time, and so do common PCB colors. Today, green is the most common. The reason? Not for any significant performance difference. Arguable, some colors may be easier on the eyes when assembling, soldering and reworking electronics, or work better with inspection optics. In reality, the main reason is probably price. Whatever is most common color will generally have lower cost, because bareboard suppliers are running that color continuously. Any odd color will require a change-over, extra clean-up, and thus additional cost.

How do I figure out the shelf life of a product?

The shelf life of a product can be found on either the technical data sheet (TDS), available on the product page, or by looking on the certificate on conformance (COC). The COC can be downloaded by going to https://www.chemtronics.com/coc. Once you have the shelf life, you will need to add it to the manufacture date for a use-by date. The manufacture date can be identified by the batch number. The batch code used on most of our products are manufacture dates in the Julian Date format. The format is YYDDD, where YY = year, DDD = day. For example, 19200 translates to the 200th day of 2019, or July 19, 2019. This webpage explains and provides charts to help interpret our batch numbers: https://www.chemtronics.com/batch-codes.
