23.3.2.9 ALIVH. The ALIVH (Any Layer Interstitial Via Hole) process has been in development for many years by Matsushita Components of Osaka, Japan. The novel process eliminates additive metallization and plating, but defines all features by subtractive etching of the copper foil. The build-up process is not sequential, though; it uses layer pairs and aramid-epoxy prepreg with copper-paste vias that can be laminated at one time into a three-dimensional structure. CMK (the second largest PCB maker in the world) and other Japanese firms have licensed the process. Six to 10 layers have been laminated in this way. 23.3.2.9.1 Structure. Figure 23.21 shows the structure and cross-sections for an ALIVH product. The PCB consists of laser-produced blind vias. The core material is an epoxy-aramid laminate. The man-made aramid filaments are ideal to be cut with a CO2 or UV laser. If the DuPont Kevlar filaments are added, then the resulting material will have a very low coefficient of thermal expansion (CTE).This is useful for mounting ceramic packages and for direct attachment of flip-chip integrated circuits. The structure can be as simple as a two-sided PCB or as complex as a many-layered PCB. The vias consist of a copper-epoxy paste that connects the top and bottom copper foil. If used as a prepreg layer without copper, the vias connect the various ALIVH layer pairs into a multilayer structure. This is not a sequential build-up process, but rather a parallel build-up process. 23.3.2.9.2 Manufacturing Process. The ALIVH process is shown in Fig. 23.22. The process starts with an epoxy-aramid B-stage prepreg. The laser cutting of holes can proceed very rapidly. The material is then printed with a conductive paste of copper and epoxy to fill these holes. Copper foil is applied and the structure is laminated to attach the foil and cure the prepreg and conductive pastes that serve as vias. The sheet of material is imaged and etched to provide the various circuits. Registration is less critical because the vias are now under the surface lands. Several of these two-sided layer pairs can be produced, inspected, and tested. The two-sided structures can then have additional single layers of B-stage/conductive paste layers with foil laminated to one or both sides, or the B-stage/conductive paste layer can be used to attach a number of layer pairs in one parallel lamination. The outside is imaged, etched, and completed as a normal PCB.

An advanced manufacturing process results in a product known as ALIVH-FB. This product has a fine-line, tight via structure suitable for wire-bonding and flip-chip substrates, as shown in Fig. 23.23. The manufacturing process for each microvia technology begins with a base core, which may be a simple double-sided board carrying power and ground planes or a multilayer board carrying some signal pattern in addition to power and ground planes. The core usually has PTHs, which become blind via holes (BVHs). Such a core is often called an active core. In fabricating a base core with a pattern, manufacturers usually panel-plate the core panel and create the pattern through a dry-film tenting process. Some makers seem to prefer pattern plating, however. The choice depends on the fabricator s familiarity with these processes. After the pattern is formed, dielectric material is laminated over the core (in the case of prepreg, with copper foil) and the holes can be filled with resins, depending on the plated hole diameter and the thickness of the core. It is generally agreed that when the diameter of plated holes is equal to or less than 0.3 mm and the core thickness is equal to 0.6 mm or less, these holes can be filled effectively by the lamination process (although the resin thickness of 80 m is preferred in the case of RCC). When the diameter and thickness conditions are not met, it is necessary to fill the holes by a separate process. A screening process does this from one side of the panel with a polyester screen that has an oversized hole pattern. After filling the holes the resin is cured completely.
