The international unified naming method for lamp and lamp socket models for film and television and stage lighting. The International Electrotechnical Commission has divided film, television photography and theater stage lighting into a professional lighting technology field. For the quartz halogen bulbs and metal halide lamps, the models of the lamp caps, lamp holders and gauges have been internationally named. The lamp holder and lamp holder models for film, television photography and stage lighting are composed of English letters and characteristic main parameter parameters that characterize their structural features. They generally consist of three parts: the first part represents the type of lamp holder and lamp holder; The two parts represent the size of the mating part of the lamp cap and the lamp holder; the third part represents the number of the lamp caps, the number of conductive contacts of the lamp holder or the number of pins. Their constituent factors are specified as follows: 1. Symbols for the types of lamp holders and lamp holders for film, television photography and stage lighting (1) Representative symbols for the types of lamp holders and lamp holders for film, television photography and stage lighting , in the following English capital letters: F - single-pin base or socket G - double-pin or multi-pin-type lamp head or lamp holder P - pre-focusing lamp holder or lamp holder Gy - behind y It means that the two pins (holes) at the lamp end are not equal in diameter. It is the same type of lamp (1) lamp holder. Some features are the same, but the lamp holder or lamp holder that cannot be interchanged can be in the lamp holder or lamp holder. There are different types of letters followed by x, y or z to distinguish them. For example, the center distance of the double pins of the G9.5 and Gx9.5 bases is 9.53mm, and the outer diameter of the pins is the same, but due to the width of the base and The thickness is different and cannot be interchanged. (Note: If necessary, add the English letters such as xx, xxy, xz, yx, yy, yz, zx, zy, and zz to the original model word line.) (3) For the socket of the lamp socket or the socket The shape is indicated by the following lowercase English letters: a - cylindrical pin (for the lamp cap) or jack (for the lamp holder) c - special shaped pin (for the lamp cap) or jack (for the lamp holder) 2, movie, TV The matching dimensions of the lamp head and the lamp holder for photographic lighting and theater stage lighting are indicated by Arabic numerals. For the pin or the lamp end is expressed as an approximation of the diameter, for the lamp holder, the approximate value of the jack diameter is used, for the pre-focusing cap sleeve outer diameter (sector and socket type) or the positioning plate outer diameter (positioning disc type) Said. 3, the number of lamp pins or the number of conductive contacts of the lamp holder or the number of pins of the lampholder's conductive contacts are indicated by lowercase English letters, as specified below: s - 1 d - 2 (without misunderstanding) The case can be omitted) t - 3 q - 4 p - 5 4, the type and size of the pin type lamp in the international standard, the type and size of the pin type lamp only indicate the lamp holder of the corresponding model The matching of the base structure and the matching size that affects its versatility and interchangeability, rather than the size of the pin type, must be enforced by the lamp manufacturer. Outside the specified shape and size range, the manufacturer can determine the type and size of other parts according to the user's needs.

PCB Prototype

Prototype PCB Specification:
In the process of developing a Printed Circuit Board-based solution for your company? This can be an extremely time-consuming, labor-intensive process where there is a high degree of uncertainty in the outcome. Developing a PCB prototype offers a fast, cost-effective option for getting your design from concept to production, while minimizing some of the risks associated with a Standard PCB service. 
Prototype Printed Circuit Boards That Meet Our High Quality Standards:
BentePCB offers rapid PCB prototyping services in very good quality yet at a low cost. We're fully compliant with ISO9001:2008 quality management systems, and we have an in-house quality control department to verify that all work meets our high standards. Depending on your custom requirements, we can prototype your PCB within 3-7 days, compared to -18 days of Standard PCB service.

 What Are the Benefits of Circuit Board Prototyping?

We recommend you chose PCB prototyping service for function testing of new products prior to making a commitment to a full-production run. Benefits of developing PCB board prototype include:

• Rapidly test and correct designs if there is any mistake

• Opportunity to detect potential design flaws in the early stages

• Quick turnaround time helps you achieve your productivity goals

• Low-quantity production runs featuring a minimum order quantity of only one boards

• Lower production tolerances provide a clear indication of how well the finished PCB will perform

Once your prototype boards demonstrated their ability to meet your quality and performance requirements, it is ready for a full production run. Then we will transition to Standard PCB service. It provides tighter production tolerances and more advanced options including free Design for Manufacture (DFM) check that is capable of detecting potential issues which could reduce the quality of your PCB.
