A Pressure Cure Oven (PCO), or Autoclave, is used to minimize voiding and increase adhesion strength for bonding processes typically used in die attach and underfill applications. PCO pressurizes air into a rigid vessel and heats & cools with
SMT 158UL is a super-fast flow capillary underfill, which can flow into 10μm gap at room temperature without preheating a substrate. After cure there is void free in underfill. The cured SMT 158UL can be easily reworked. SMT 158UL not only can be use

We are experiencing voiding on one of our lead-free assemblies on every part. The voiding only occurs underneath the parts and not in the solder fillet (see pic). We have tried baking, curing, washing, multiple pastes and everything else we can think

Wait...stop! Some adhesives will void when cured... some common branks... maybe already mentioned. Heraeus PD955 will minimize voiding when curing the adhesive. Voiding can have devestating consequences....learned from experience. Another key is kee

Void Formation in Solder Joints – Causes & Cures Webinar Monday 18th May 2.30pm GMT Voiding in solder joints is not new we have experienced cavities in solder joints during the introduction of through hole, surface mount and more recently area array technology. In many cases we never knew we have had voids till the introduction of x-ray inspection.

Isola Group has launched a technology-licensing program to mitigate conductive anodic filamentation (CAF) problems in the fabrication of PCBs. This proprietary manufacturing technology, which is offered by ISOLA USA Corp. "Isola USA", reduces the number of voids in resin-impregnated dielectrics, which is a major source of CAF failures.

The present work offers a discussion and a first case study to identify and illustrate voiding mechanisms for a particular TIM between a heat spreader and the back of a flip chip. Pronounced differences were observed between stencil printing and dispensing in terms of initial void formation, apparently related to the specific properties of the material. Measurements of the effects of heat ramp rate and peak temperature showed the subsequent evolution and final void size distribution to be determined by the initial part of the cure profile up to the material gelling temperature.
