Next, the staff experienced enough to handle the challenge of manufacturing flexible boards. Opening a solder mask or overlay enough-different steps of the process might change how a flexible board looks. Etching and plating can adjust the shape of the PCB, which is why you should ensure that overlay openings are of suitable width.Choose the materials carefully, also considering other things, such as size, weight, and reliability of the board.Control appropriate proximity of solder joints and bending point - the solder joint should be at the required distance from the bending location. If you put them too close, delamination or broken solder pad may occur.Control Solder pad spacing - ABIS ensuring there is enough space between the pads and the conductive traces adjacent to them, so that avoiding lamination loss.  Our Advantages Our AdvantagesHigh-end euipment-high speed Pick and Place Machines that can process about 25,000 SMD components per hourHigh efficient supply ability 60K Sqm monthly-Offers low volume and on-demand PCB production, also large-scale productionProfessional engineering team-40 engineers and their own tooling house, strong at OEM.
