What is the Expected Shelf Life of ESD Control Bags? There are many ways to manufacture an ESD shielding bag with low charging properties on the inner and outer layers. This is the first factor to consider. Some processes achieve shielding values via a buried metal layer. The metal layer is laminated between two layers…
If you need to avoid baking your surface mount devices (SMD) before solder reflow, storing them in proper dry packaging will be required. A dry package typically consists of three components; an MBB, desiccant, and humidity indicator card (HIC). To determine how dry the package should be, you need to determine your MSL (moisture sensitivity…
Setting up a new ESD Protected Area (EPA) can be a little daunting, especially if you are unfamiliar or relatively new to the concept of ESD Control. It would be nice to have a blue print for establishing an EPA, but in truth there is no exact formula as everyone’s situation is different. However, there…

Each component in an ESD protected area (EPA) plays a vital part in the fight against electrostatic discharge (ESD). If just one component is not performing correctly, you could harm your ESD sensitive devices, potentially costing your company a lot of money. The problem with many ESD protective products is that you can’t always see…

1. Define what you are trying to protect. What is the Human-Body Model (HBM) withstand voltage of the most sensitive item? A prerequisite of ESD control is the accurate and consistent identification of ESD susceptible items. Some companies assume that all electronic components are ESD susceptible. However, others write their ESD control plan based on…

Antistatic is the ESD control property properly referred to as “low charging”. This is an important property for all bags used inside or outside of an ESD protected area (EPA). Specifically, it is important that the inside of the bag be low charging, so when the ESD Sensitive Device is inserted into the bag or…

While there is no direct link between protection from ESD and protection from moisture, many devices and components require protection from both. Statshield Moisture Barrier Bags (MBB) are designed to protect the contents from both moisture and ESD events. MBBs protect ESD susceptible devices by forming a faraday cage around the contents and they protect…
