The alternative is by looking at all your components data specs (heat-range), especially pay more attentions to heat-sensitive comps, and fine-pitch comps, odd-form comps, draw a diagram on a separate sheet of paper shown that temperature VS those ca

The question is can you consistently heat up the board to the desired temperature? You need to measure temperature with thermocouples and plot temp/time diagram. Based on the datasheet chemistry you use, you can see what is the recommendation and if

When the current flows through the stator winding, the stator winding produces a vector magnetic field. The magnetic field will drive the rotor to rotate an angle, so that the direction of magnetic fields of the rotor is consistent with that of the stator. When the vector magnetic field of the stator rotates an angle, the rotor also rotates at an angle with this magnetic field. Every input of an electric pulse leads the motor to rotate at an angle to advance one step. The angular displacement of the output is proportional to the number of pulses input, and the speed is proportional to the pulse frequency.

The use of desiccant bags filled with Silica Sand and or Clay beads used in conjunction with a Moisture Barrier Bag to control moisture for storage of printed circuit boards has long been an accepted practice and standard from both JEDEC and IPC organizations. Additionally, the use heated ovens for baking off moisture using the evaporation process has also been a long#2;standing practice from these organizations. This paper on alternative drying methods will be accompanied by completed independent, unbiased tests conducted by Vinny Nguyen, an engineering student (now graduated) from San Jose State University. The accompanied paper will examine the performance levels of different technologies of desiccant bags to control moisture in enclosed spaces. The tests and equipment set were reviewed by an engineer and consultant to the Lockheed Martin Aerospace Division and the IPC - TM-650 2.6.28 test method was review by engineer from pSemi. The tests were designed to mimic performance tests outlined in Mil Spec 3464, which both IPC and JEDEC have adopted for their respective standards. The test examined variables including absorption capacity rates, weight gain and release of moisture back into the enclosed area. The presentation will also address and highlight: • Similarities of PCBs and Heavy Equipment as it applies to Inspections, Causes of Failure, Types of Corrosion and Moisture Collection Points. • Performance Attributes of Different Desiccant Technologies as it applies to shape, texture, change outs, labeling and regeneration. • Venn Diagram of Electromechanical Failure with the circles 1. Current 2. Contamination 3. Humidity Presentation Available
