Repairing these PCBs was not an option due to the delivery amount. Oxidation is unlikely, as these anomalies were visible right after unpacking them and the humidity card was not suspicious. We have since decided not to use these PCBs as the risks w

Chris, you are not completely right. Our industrial is following the IPC standard as our guideline. Per IPC J-STD-033 has specify the floor life at para. 8 (normal condition at 30C/60%RH). If Victor can control his environment at 32% then the compo

Another important element to consider is the impact of ambient temperature and humidity on Moisture Sensitive Components. The majority of plastic encapsulated ICs are classified as moisture-sensitive devices (MSD). This means that they are qualifie

We want to handle the materials such as PCB & MSD components as per IPC 1601 & J-STD-033. As such, we need a baking oven to perform this and to monitor (temperature – we have to maintain up to 200’C & humidity – below 5%)the control environment & ma

Joe: Hey, just hose everyone down with water when your humidity starts to decrease to below 40%. ;-) Actually, that�s how some humidity controllers work, when added to your heating system. Well basically that�s how they work. I�m not tryin� to

1. Floor loading requirement - The designer of your factory building specified the flooring with a certain floor loading capability. You need to determine that capability. You plan to install machines and equipment. You need to determine the weight o

I have been asked to supply a maximum shelf life for our assemblied PCB's. I realise this is dependent on so many factors- temperature, humidity, no of layers etc. But does anyone have a formulae for calculating shelf life, or does anyone know of a s

We have now switched to Kester EP256. During our solder paste evaluation, resistance to humidity was one of the selection criteria. We printed multiple boards, then exposed them to 85�F/65% RH. At 30 minutes, 1 hour, 2 hours, and 4 hours exposure
