The effectiveness of production manufacturing
personnel is key to our success. Until now, there has not been a publication
written for use in training the production personnel that we hire to
assemble SMT products. It is the first book to break down technical
terms so they can be understood by non-technical personnel. This publication,
written by two of the industry's leading experts, does an excellent
job informing them about what is required to do SMT and proves to be
a valuable reference book. It has proven to improve efficiency and contribution.
Building SMT products is significantly different from leaded technology
products. Included is information in straight forward terms on SMT components,
process changes, steps in handling and building SMT and mixed SMT/leaded
assemblies. The standards that we use are explained, plus information
on inspection, techniques, soldering and fixing the assemblies.
Training personnel? This is the publication for you!
