In fact, they drive up costs and make products less reliable. They are causing American companies to send their work to low labor cost countries. They condition employees to accept practices like touchup and rework that increase failure rates as well as inflate labor costs. If the way in which these standards are used does not change radically, electronics manufacturing may completely disappear in this country.

There are approximate J-Std equivalents and Kester or Cookson can help you with this. Any negative impact recorded at IPC since the use of solder paste with H type flux and so that corrective action taken? I have no idea. What does your SOW or contract say?

What type of water soluble solder paste preferable for Class III applications? Typical testing includes but may not be limited to depending on your customer surface insulation resistance SIR and visual inspection for corrosion, dendrite formation and measeling of conformal. Do IPC suggest any specific method to measure the thickness of the solder paste on the PWB before beginning the process? Solder thickness is a function of aperture size, stencil thickness and paste viscosity amongst other things.

Excessive paste may result in excessive solder on the joints and possibly shorts while to little paste will result in insufficient both rejectable in the J-Std.

You ned to determine the the paste thickness required for your process in the development stages. See the following links for more information:.

As a result of this expansion the substrate, the die, or the wire bonds could be damaged. The damage is often invisible and requires X-ray equipment to conduct a proper analysis. When the anti-static bag is opened and the ICs are exposed to ambient conditions, the moisture in the air is trapped inside the device. This means that during the PCB assembly process e. The bags shall be heat sealable. Desiccant shall be dustless, non-corrosive, and absorbent to amounts specified in the standard.
