Introduction
Tenting process is a kind of subtractive process, the process as follows: Laminating photosensitive film resist over conductor layer and metallized holes/vias, and forming the circuits pattern on photosensitive film after exposing and developing; and then forming the circuits pattern on the conductor by etching. As circuits pattern is etching on the conductor Layer, the thicker the conductor, the more etching needed. The capability of fine line/space forming of Tenting is lower than SAP & msap.
Tenting process is the most widely used in PCB industry, the technical difficulty is low, the pattern forming process is as follow

SAPใMSAP and Tenting are three kinds of mainly processes in PCB industry, and each has its own advantages and disadvantages. And the processes are constantly evolving and advancing. In a lot of different applications, the boundaries between the processes are blurred, and could be used in combination sometimes. QHIC has SAPใMSAP and Tenting process with well-rounded technology, and can provide high-quality low-cost solutions according to customers’ needs

Supports advanced nodes such as [5-22nm FinFET/BCD/GAA] to meet the needs of high-performance computing (HPC), AI chips, etc.
MPW (Multi-Project Wafer) Service: Small batch trial production to reduce customers' initial costs. Customized process development: Cooperate with customers to conduct DTCO (Design-Process Co-Optimization), customize design rules and process parameters.
We support the joint solution of "wafer foundry + advanced packaging" (such as 3D IC, heterogeneous integration) to avoid the loss of multi-supplier collaboration. Unlike pure foundries, we verify the process stability through mass production of our own chips to reduce the risk of tape-out for you.
