Custom HDI Printed Circuit Board Manufacturing China Supplier

HDI PCB Introduction

-Definition

-Applications

HDI PCB is used to reduce size and weight, as well as to enhance electrical performance of the device. HDI PCB is the best alternative to high layer-count and expensive standard laminate or sequentially laminated boards. HDI incorporate blind and buried vias that help to save PCB real estate by allowing features and lines to be designed above or below them without making a connection. Many of today's fine pitch BGA and flip-chip component footprints do not allow for running traces between the BGA pads. Blind and buried vias will only connect layers requiring connections in that area.

Where does the resin material come from in ABIS?

Most of them from Shengyi Technology Co., Ltd. (SYTECH), who has been the world's second largest CCL manufacturer in terms of sales volume, from 2013 to 2017. We established long-term relations of cooperation since 2006. The FR4 resin material (Model S1000-2, S1141, S1165, S1600) are mainly used for making single and double-sided printed circuit boards as well as multi-layer boards. Here comes details for your reference.

• For FR-4: Sheng Yi, King Board, Nan Ya, Polycard, ITEQ, ISOLA

• For CEM-1 & CEM 3: Sheng Yi, King Board

• For High Frequency : Sheng Yi

• For UV Cure:  Tamura, Chang Xing ( * Available colour : Green) Solder for Single Side

• For Liquid Photo: Tao Yang, Resist (Wet Film)

• Chuan Yu ( * Available colours : White, Imaginable Solder Yellow, Purple, Red, Blue, Green,  Black)

Rigid PCB Manufacturing Capacity

ABIS experienced in making special materials for rigid PCB, such as: CEM-1/CEM-3, PI, High Tg, Rogers, PTEF, Alu/Cu Base, etc. Below is a brief overview FYI.

PCB Manufacturing Process

• The process starts with designing Layout of the PCB using any PCB designing software / CAD Tool (Proteus, Eagle, Or CAD).

• All rest of the steps are of Manufacturing Process of a Rigid Printed Circuit Board is same as Single Sided PCB or Double Sided PCB or Multi-layer PCB.

PCB Lead Time

-Hole Preparation

Removing debris carefully & adjusting drill machine parameters: before plating through with copper, abis pays high attention to all holes on an fr4 pcb treated to remove debris, surface irregularities, and epoxy smear, the clean holes ensure the plating successfully adheres to the hole walls. also, early in the process, drill machine parameters are adjusted accurately.

- Surface Preparation

Deburring carefully: our experienced tech workers will be aware ahead of time that the only way to avoid a bad outcome is to anticipate the need for special handling and to take the appropriate steps to be sure that the process is done carefully and correctly.

-Thermal Expansion Rates

Accustomed to dealing with the various materials, abis will be able to analyze the combination to be sure that it is appropriate. then keeping the long-term reliability of the cte (coefficient of thermal expansion), with the lower cte, the less likely the plated through holes are to fail from repeated flexing of the copper which forms the internal layer interconnections.

-Scaling

Abis control the circuitry is scaled-up by known percentages in anticipation of this loss so that the layers will return to their as-designed dimensions after the lamination cycle is complete. also, using the laminate manufacturer’s baseline scaling recommendations in combination with in-house statistical process control data, to dial-in scale factors that will be consistent over time within that particular manufacturing environment.

 

-Machining

When the time comes to build your pcb, abis be sure that you choose has the right equipment and experience to produce it correctly on the first try.
